Hello @MastodonEngineering,

I wanted to share some feedback on the documentation provided in the Highlighting Journalism on Mastodon blog post.

Specifically, in The technical section, the example code for the fediverse:creator meta tag is given as:

<meta name="fediverse:creator" content="@Gargron@mastodon.social" />

Based on my testing (and that of others), Mastodon doesn't seem to recognize the creator link correctly when the leading @ is present in the content attribute. It only works when the @ is removed, like this:

<meta name="fediverse:creator" content="Gargron@mastodon.social" />

Following the blog's example directly led to some wasted time figuring out why it wasn't working. It would be great if either the example in the blog post could be corrected to reflect the current requirement, or if Mastodon's parser could be made more flexible to accept the handle with or without the leading @.

Appreciate all you do for #Mastodon!

#fedidev #fediverse

We're excited to announce the release of Fedify 1.5.0! This version brings several significant improvements to performance, configurability, and developer experience. Let's dive into what's new:

Two-Stage Fan-out Architecture for Efficient Activity Delivery

#Fedify now implements a smart fan-out mechanism for delivering activities to large audiences. This change is particularly valuable for accounts with many followers. When sending activities to many recipients, Fedify now creates a single consolidated message containing the activity payload and recipient list, which a background worker then processes to re-enqueue individual delivery tasks.

This architectural improvement delivers several benefits: Context.sendActivity() returns almost instantly even with thousands of recipients, memory consumption is dramatically reduced by avoiding payload duplication, UI responsiveness improves since web requests complete quickly, and the system maintains reliability with independent retry logic for each delivery.

For specific requirements, we've added a new fanout option with three settings:

// Configuring fan-out behavior
await ctx.sendActivity(
  { identifier: "alice" },
  recipients,
  activity,
  { fanout: "auto" }  // Default: automatic based on recipient count
  // Other options: "skip" (never use fan-out) or "force" (always use fan-out)
);

Canonical Origin Support for Multi-Domain Setups

You can now explicitly configure a canonical origin for your server, which is especially useful for multi-domain setups. This feature allows you to set different domains for WebFinger handles and #ActivityPub URIs, configured through the new origin option in createFederation(). This enhancement prevents unexpected URL construction when requests bypass proxies and improves security by ensuring consistent domain usage.

const federation = createFederation({
  // Use example.com for handles but ap.example.com for ActivityPub URIs
  origin: {
    handleHost: "example.com",
    webOrigin: "https://ap.example.com",
  },
  // Other options...
});

Optional Followers Collection Synchronization

Followers collection synchronization (FEP-8fcf) is now opt-in rather than automatic. This feature must now be explicitly enabled through the syncCollection option, giving developers more control over when to include followers collection digests. This change improves network efficiency by reducing unnecessary synchronization traffic.

await ctx.sendActivity(
  { identifier: sender },
  "followers",
  activity,
  { 
    preferSharedInbox: true,
    syncCollection: true,  // Explicitly enable collection synchronization
  }
);

Enhanced Key Format Compatibility

Key format support has been expanded for better interoperability. Fedify now accepts PEM-PKCS#1 format in addition to PEM-SPKI for RSA public keys. We've added importPkcs1() and importPem() functions for additional flexibility, which improves compatibility with a wider range of ActivityPub implementations.

Improved Key Selection Logic

The key selection process is now more intelligent. The fetchKey() function can now select the public key of an actor if keyId has no fragment and the actor has only one public key. This enhancement simplifies key handling in common scenarios and provides better compatibility with implementations that don't specify fragment identifiers.

New Authorization Options

Authorization handling has been enhanced with new options for the RequestContext.getSignedKey() and getSignedKeyOwner() methods. This provides more flexible control over authentication and authorization flows. We've deprecated older parameter-based approaches in favor of the more flexible method-based approach.

Efficient Bulk Message Queueing

Message queue performance is improved with bulk operations. We've added an optional enqueueMany() method to the MessageQueue interface, enabling efficient queueing of multiple messages in a single operation. This reduces overhead when processing batches of activities. All our message queue implementations have been updated to support this new operation:

• @fedify/redis 0.4.0
• @fedify/postgres 0.3.0
• @fedify/amqp 0.2.0

If you're using any of these packages, make sure to update them alongside Fedify to take advantage of the more efficient bulk message queueing.

CLI Improvements

The Fedify command-line tools have been enhanced with an improved web interface for the fedify inbox command. We've added the Fedify logo with the cute dinosaur at the top of the page and made it easier to copy the fediverse handle of the ephemeral actor. We've also fixed issues with the web interface when installed via deno install from JSR.

Additional Improvements and Bug Fixes

• Updated dependencies, including @js-temporal/polyfill to 0.5.0 for Node.js and Bun
• Fixed bundler errors with uri-template-router on Rollup
• Improved error handling and logging for document loader when KV store operations fail
• Added more log messages using the LogTape library
• Internalized the multibase package for better maintenance and compatibility

For the complete list of changes, please refer to the changelog.

To update to Fedify 1.5.0, run:

# For Deno
deno add jsr:@fedify/fedify@1.5.0

# For npm
npm  add     @fedify/fedify@1.5.0

# For Bun
bun  add     @fedify/fedify@1.5.0

Thank you to all contributors who helped make this release possible!

#fedidev #fediverse

I received a heartwarming #testimonial about #Fedify today!

@bgl shared in the FediDev KR Discord server:

I had trouble finding good resources explaining ActivityPub, but after reading through the Fedify docs from start to finish, I feel like I've actually digested it.

They also posted on their Hackers' Pub:

If you want to learn ActivityPub efficiently, just read the Fedify docs from beginning to end.

This makes all the documentation work worthwhile. Glad our docs are helping people understand not just Fedify, but #ActivityPub itself.

#fedidev #fediverse

The ActivityPub specification does not have an example of the "sharedInbox" field in use.

Although it does say "An optional endpoint..." — I suspect a lot of people won't know (with confidence) that it can go under the "endpoints" field. For example:

"endpoints": {
"sharedInbox": "https://social.example/inbox"
},

Especially if the person is still trying to understand ActivityPub, and isn't aware of the "endpoints" field yet.

#ActivityPub #DeSo #FediDev #FediDevs #Fediverse #SharedInbox

A reasonable ActivityPub / ActivityStreams API to schedule something to be posted in the future might be — to HTTP POST something to an account's outbox with the `published` field set to a date-time in the future.

#fedidev #fediverse

Currently, the way I am determining if content is valid ActivityPub / ActivityStreams content is —

№1:

Determining if it is valid JSON.

№2:

Checking if it has a "type" field.

And that is it.

#ActivityPub #ActivityStreams #DeSo #FediDev #FediDevs #Fediverse #JSONLD

Dealing with JSON-LD would be easier in many ways if everything was defined inline.

Rather than having to get the content from a URL in the context, parse it, etc.

I've been thinking of contributing to the #fediverse for a while now, but I haven't really found a project or an idea that would fit my tech stack requirements yet.

Like Pixelfed and Loops have a PHP backend, but I'd rather contribute something with Golang or Typescript/Javascript.

Does anyone have some ideas?

Two-Stage Fan-out Architecture for Efficient Activity Delivery

#Fedify now implements a smart fan-out mechanism for delivering activities to large audiences. This change is particularly valuable for accounts with many followers. When sending activities to many recipients, Fedify now creates a single consolidated message containing the activity payload and recipient list, which a background worker then processes to re-enqueue individual delivery tasks.

This architectural improvement delivers several benefits: Context.sendActivity() returns almost instantly even with thousands of recipients, memory consumption is dramatically reduced by avoiding payload duplication, UI responsiveness improves since web requests complete quickly, and the system maintains reliability with independent retry logic for each delivery.

For specific requirements, we've added a new fanout option with three settings:

// Configuring fan-out behavior
await ctx.sendActivity(
  { identifier: "alice" },
  recipients,
  activity,
  { fanout: "auto" }  // Default: automatic based on recipient count
  // Other options: "skip" (never use fan-out) or "force" (always use fan-out)
);

Canonical Origin Support for Multi-Domain Setups

You can now explicitly configure a canonical origin for your server, which is especially useful for multi-domain setups. This feature allows you to set different domains for WebFinger handles and #ActivityPub URIs, configured through the new origin option in createFederation(). This enhancement prevents unexpected URL construction when requests bypass proxies and improves security by ensuring consistent domain usage.

const federation = createFederation({
  // Use example.com for handles but ap.example.com for ActivityPub URIs
  origin: {
    handleHost: "example.com",
    webOrigin: "https://ap.example.com",
  },
  // Other options...
});

Optional Followers Collection Synchronization

Followers collection synchronization (FEP-8fcf) is now opt-in rather than automatic. This feature must now be explicitly enabled through the syncCollection option, giving developers more control over when to include followers collection digests. This change improves network efficiency by reducing unnecessary synchronization traffic.

await ctx.sendActivity(
  { identifier: sender },
  "followers",
  activity,
  { 
    preferSharedInbox: true,
    syncCollection: true,  // Explicitly enable collection synchronization
  }
);

Enhanced Key Format Compatibility

Key format support has been expanded for better interoperability. Fedify now accepts PEM-PKCS#1 format in addition to PEM-SPKI for RSA public keys. We've added importPkcs1() and importPem() functions for additional flexibility, which improves compatibility with a wider range of ActivityPub implementations.

Improved Key Selection Logic

The key selection process is now more intelligent. The fetchKey() function can now select the public key of an actor if keyId has no fragment and the actor has only one public key. This enhancement simplifies key handling in common scenarios and provides better compatibility with implementations that don't specify fragment identifiers.

New Authorization Options

Authorization handling has been enhanced with new options for the RequestContext.getSignedKey() and getSignedKeyOwner() methods. This provides more flexible control over authentication and authorization flows. We've deprecated older parameter-based approaches in favor of the more flexible method-based approach.

Efficient Bulk Message Queueing

Message queue performance is improved with bulk operations. We've added an optional enqueueMany() method to the MessageQueue interface, enabling efficient queueing of multiple messages in a single operation. This reduces overhead when processing batches of activities. All our message queue implementations have been updated to support this new operation:

• @fedify/redis 0.4.0
• @fedify/postgres 0.3.0
• @fedify/amqp 0.2.0

If you're using any of these packages, make sure to update them alongside Fedify to take advantage of the more efficient bulk message queueing.

CLI Improvements

The Fedify command-line tools have been enhanced with an improved web interface for the fedify inbox command. We've added the Fedify logo with the cute dinosaur at the top of the page and made it easier to copy the fediverse handle of the ephemeral actor. We've also fixed issues with the web interface when installed via deno install from JSR.

Additional Improvements and Bug Fixes

• Updated dependencies, including @js-temporal/polyfill to 0.5.0 for Node.js and Bun
• Fixed bundler errors with uri-template-router on Rollup
• Improved error handling and logging for document loader when KV store operations fail
• Added more log messages using the LogTape library
• Internalized the multibase package for better maintenance and compatibility

For the complete list of changes, please refer to the changelog.

I had trouble finding good resources explaining ActivityPub, but after reading through the Fedify docs from start to finish, I feel like I've actually digested it.

They also posted on their Hackers' Pub:

If you want to learn ActivityPub efficiently, just read the Fedify docs from beginning to end.

This makes all the documentation work worthwhile. Glad our docs are helping people understand not just Fedify, but #ActivityPub itself.

#fedidev #fediverse

I've been thinking of contributing to the #fediverse for a while now, but I haven't really found a project or an idea that would fit my tech stack requirements yet.

Like Pixelfed and Loops have a PHP backend, but I'd rather contribute something with Golang or Typescript/Javascript.

Does anyone have some ideas?

We're excited to announce the release of Fedify 1.5.0! This version brings several significant improvements to performance, configurability, and developer experience. Let's dive into what's new:

#Fedify now implements a smart fan-out mechanism for delivering activities to large audiences. This change is particularly valuable for accounts with many followers. When sending activities to many recipients, Fedify now creates a single consolidated message containing the activity payload and recipient list, which a background worker then processes to re-enqueue individual delivery tasks.

This architectural improvement delivers several benefits: Context.sendActivity() returns almost instantly even with thousands of recipients, memory consumption is dramatically reduced by avoiding payload duplication, UI responsiveness improves since web requests complete quickly, and the system maintains reliability with independent retry logic for each delivery.

For specific requirements, we've added a new fanout option with three settings:

// Configuring fan-out behavior
await ctx.sendActivity(
  { identifier: "alice" },
  recipients,
  activity,
  { fanout: "auto" }  // Default: automatic based on recipient count
  // Other options: "skip" (never use fan-out) or "force" (always use fan-out)
);

Canonical Origin Support for Multi-Domain Setups

You can now explicitly configure a canonical origin for your server, which is especially useful for multi-domain setups. This feature allows you to set different domains for WebFinger handles and #ActivityPub URIs, configured through the new origin option in createFederation(). This enhancement prevents unexpected URL construction when requests bypass proxies and improves security by ensuring consistent domain usage.

const federation = createFederation({
  // Use example.com for handles but ap.example.com for ActivityPub URIs
  origin: {
    handleHost: "example.com",
    webOrigin: "https://ap.example.com",
  },
  // Other options...
});

Optional Followers Collection Synchronization

Followers collection synchronization (FEP-8fcf) is now opt-in rather than automatic. This feature must now be explicitly enabled through the syncCollection option, giving developers more control over when to include followers collection digests. This change improves network efficiency by reducing unnecessary synchronization traffic.

await ctx.sendActivity(
  { identifier: sender },
  "followers",
  activity,
  { 
    preferSharedInbox: true,
    syncCollection: true,  // Explicitly enable collection synchronization
  }
);

Enhanced Key Format Compatibility

Key format support has been expanded for better interoperability. Fedify now accepts PEM-PKCS#1 format in addition to PEM-SPKI for RSA public keys. We've added importPkcs1() and importPem() functions for additional flexibility, which improves compatibility with a wider range of ActivityPub implementations.

The key selection process is now more intelligent. The fetchKey() function can now select the public key of an actor if keyId has no fragment and the actor has only one public key. This enhancement simplifies key handling in common scenarios and provides better compatibility with implementations that don't specify fragment identifiers.

We're excited to announce the release of Fedify 1.5.0! This version brings several significant improvements to performance, configurability, and developer experience. Let's dive into what's new:

Two-Stage Fan-out Architecture for Efficient Activity Delivery

#Fedify now implements a smart fan-out mechanism for delivering activities to large audiences. This change is particularly valuable for accounts with many followers. When sending activities to many recipients, Fedify now creates a single consolidated message containing the activity payload and recipient list, which a background worker then processes to re-enqueue individual delivery tasks.

This architectural improvement delivers several benefits: Context.sendActivity() returns almost instantly even with thousands of recipients, memory consumption is dramatically reduced by avoiding payload duplication, UI responsiveness improves since web requests complete quickly, and the system maintains reliability with independent retry logic for each delivery.

For specific requirements, we've added a new fanout option with three settings:

// Configuring fan-out behavior
await ctx.sendActivity(
  { identifier: "alice" },
  recipients,
  activity,
  { fanout: "auto" }  // Default: automatic based on recipient count
  // Other options: "skip" (never use fan-out) or "force" (always use fan-out)
);

Canonical Origin Support for Multi-Domain Setups

You can now explicitly configure a canonical origin for your server, which is especially useful for multi-domain setups. This feature allows you to set different domains for WebFinger handles and #ActivityPub URIs, configured through the new origin option in createFederation(). This enhancement prevents unexpected URL construction when requests bypass proxies and improves security by ensuring consistent domain usage.

const federation = createFederation({
  // Use example.com for handles but ap.example.com for ActivityPub URIs
  origin: {
    handleHost: "example.com",
    webOrigin: "https://ap.example.com",
  },
  // Other options...
});

Optional Followers Collection Synchronization

Followers collection synchronization (FEP-8fcf) is now opt-in rather than automatic. This feature must now be explicitly enabled through the syncCollection option, giving developers more control over when to include followers collection digests. This change improves network efficiency by reducing unnecessary synchronization traffic.

await ctx.sendActivity(
  { identifier: sender },
  "followers",
  activity,
  { 
    preferSharedInbox: true,
    syncCollection: true,  // Explicitly enable collection synchronization
  }
);

Enhanced Key Format Compatibility

Key format support has been expanded for better interoperability. Fedify now accepts PEM-PKCS#1 format in addition to PEM-SPKI for RSA public keys. We've added importPkcs1() and importPem() functions for additional flexibility, which improves compatibility with a wider range of ActivityPub implementations.

Improved Key Selection Logic

The key selection process is now more intelligent. The fetchKey() function can now select the public key of an actor if keyId has no fragment and the actor has only one public key. This enhancement simplifies key handling in common scenarios and provides better compatibility with implementations that don't specify fragment identifiers.

New Authorization Options

Authorization handling has been enhanced with new options for the RequestContext.getSignedKey() and getSignedKeyOwner() methods. This provides more flexible control over authentication and authorization flows. We've deprecated older parameter-based approaches in favor of the more flexible method-based approach.

Efficient Bulk Message Queueing

Message queue performance is improved with bulk operations. We've added an optional enqueueMany() method to the MessageQueue interface, enabling efficient queueing of multiple messages in a single operation. This reduces overhead when processing batches of activities. All our message queue implementations have been updated to support this new operation:

• @fedify/redis 0.4.0
• @fedify/postgres 0.3.0
• @fedify/amqp 0.2.0

If you're using any of these packages, make sure to update them alongside Fedify to take advantage of the more efficient bulk message queueing.

CLI Improvements

The Fedify command-line tools have been enhanced with an improved web interface for the fedify inbox command. We've added the Fedify logo with the cute dinosaur at the top of the page and made it easier to copy the fediverse handle of the ephemeral actor. We've also fixed issues with the web interface when installed via deno install from JSR.

Additional Improvements and Bug Fixes

• Updated dependencies, including @js-temporal/polyfill to 0.5.0 for Node.js and Bun
• Fixed bundler errors with uri-template-router on Rollup
• Improved error handling and logging for document loader when KV store operations fail
• Added more log messages using the LogTape library
• Internalized the multibase package for better maintenance and compatibility

For the complete list of changes, please refer to the changelog.

Key format support has been expanded for better interoperability. Fedify now accepts PEM-PKCS#1 format in addition to PEM-SPKI for RSA public keys. We've added importPkcs1() and importPem() functions for additional flexibility, which improves compatibility with a wider range of ActivityPub implementations.

Improved Key Selection Logic

The key selection process is now more intelligent. The fetchKey() function can now select the public key of an actor if keyId has no fragment and the actor has only one public key. This enhancement simplifies key handling in common scenarios and provides better compatibility with implementations that don't specify fragment identifiers.

New Authorization Options

Authorization handling has been enhanced with new options for the RequestContext.getSignedKey() and getSignedKeyOwner() methods. This provides more flexible control over authentication and authorization flows. We've deprecated older parameter-based approaches in favor of the more flexible method-based approach.

Efficient Bulk Message Queueing

Message queue performance is improved with bulk operations. We've added an optional enqueueMany() method to the MessageQueue interface, enabling efficient queueing of multiple messages in a single operation. This reduces overhead when processing batches of activities. All our message queue implementations have been updated to support this new operation:

• @fedify/redis 0.4.0
• @fedify/postgres 0.3.0
• @fedify/amqp 0.2.0

If you're using any of these packages, make sure to update them alongside Fedify to take advantage of the more efficient bulk message queueing.

CLI Improvements

The Fedify command-line tools have been enhanced with an improved web interface for the fedify inbox command. We've added the Fedify logo with the cute dinosaur at the top of the page and made it easier to copy the fediverse handle of the ephemeral actor. We've also fixed issues with the web interface when installed via deno install from JSR.

Additional Improvements and Bug Fixes

• Updated dependencies, including @js-temporal/polyfill to 0.5.0 for Node.js and Bun
• Fixed bundler errors with uri-template-router on Rollup
• Improved error handling and logging for document loader when KV store operations fail
• Added more log messages using the LogTape library
• Internalized the multibase package for better maintenance and compatibility

For the complete list of changes, please refer to the changelog.

#fedidev #fediverse

We're excited to announce the release of Fedify 1.5.0! This version brings several significant improvements to performance, configurability, and developer experience. Let's dive into what's new:

Two-Stage Fan-out Architecture for Efficient Activity Delivery

#Fedify now implements a smart fan-out mechanism for delivering activities to large audiences. This change is particularly valuable for accounts with many followers. When sending activities to many recipients, Fedify now creates a single consolidated message containing the activity payload and recipient list, which a background worker then processes to re-enqueue individual delivery tasks.

This architectural improvement delivers several benefits: Context.sendActivity() returns almost instantly even with thousands of recipients, memory consumption is dramatically reduced by avoiding payload duplication, UI responsiveness improves since web requests complete quickly, and the system maintains reliability with independent retry logic for each delivery.

For specific requirements, we've added a new fanout option with three settings:

// Configuring fan-out behavior
await ctx.sendActivity(
  { identifier: "alice" },
  recipients,
  activity,
  { fanout: "auto" }  // Default: automatic based on recipient count
  // Other options: "skip" (never use fan-out) or "force" (always use fan-out)
);

Canonical Origin Support for Multi-Domain Setups

You can now explicitly configure a canonical origin for your server, which is especially useful for multi-domain setups. This feature allows you to set different domains for WebFinger handles and #ActivityPub URIs, configured through the new origin option in createFederation(). This enhancement prevents unexpected URL construction when requests bypass proxies and improves security by ensuring consistent domain usage.

const federation = createFederation({
  // Use example.com for handles but ap.example.com for ActivityPub URIs
  origin: {
    handleHost: "example.com",
    webOrigin: "https://ap.example.com",
  },
  // Other options...
});

Optional Followers Collection Synchronization

Followers collection synchronization (FEP-8fcf) is now opt-in rather than automatic. This feature must now be explicitly enabled through the syncCollection option, giving developers more control over when to include followers collection digests. This change improves network efficiency by reducing unnecessary synchronization traffic.

await ctx.sendActivity(
  { identifier: sender },
  "followers",
  activity,
  { 
    preferSharedInbox: true,
    syncCollection: true,  // Explicitly enable collection synchronization
  }
);

The ActivityPub specification does not have an example of the "sharedInbox" field in use.

Although it does say "An optional endpoint..." — I suspect a lot of people won't know (with confidence) that it can go under the "endpoints" field. For example:

"endpoints": {
"sharedInbox": "https://social.example/inbox"
},

Especially if the person is still trying to understand ActivityPub, and isn't aware of the "endpoints" field yet.

New API filter action in Mastodon that fedi app developers will want to know about.

Filters can now include a new filter_action of “blur”. Media attachments in posts matching the criteria should then be blurred by the client app based on the FilterResult object attached.

I just discovered why some of my followers from larger #Mastodon instances (like mastodon.social) would mysteriously unfollow me after a while!

A pull request was just merged in Mastodon that fixes a critical bug in their follower synchronization mechanism.

Turns out Mastodon implements the FEP-8fcf specification (Followers collection synchronization across servers), but it expected all followers to be in a single page collection. When followers were split across multiple pages, it would only see the first page and incorrectly remove all followers from subsequent pages!

This explains so much about the strange behavior I've been seeing with #Hollo and other #Fedify-based servers over the past few months. Some people would follow me from large instances, then mysteriously unfollow later without any action on their part.

Thankfully this fix has been marked for backporting, so it should appear in an upcoming patch release rather than waiting for the next major version. Great news for all of us building on #ActivityPub!

This is why I love open source—we can identify, understand, and fix these kinds of interoperability issues together. 😊

I think there is a need for a "dumb" document format.

HTML is no longer that.

Markdown probably isn't it.

No one really uses enriched-text (IETF RFC 1896).

(I prefer wiki like formats, for various reasons, but —)

I don't think there is an obvious choice for a "dumb" document format, right now.

I think HTML being the default content type for ActivityPub / ActivityStreams is unfortunate in some ways.

HTML was originally a "dumb" document format. But, it is now a "smart" application format — with privacy & security concerns.

https://mastodon.social/@reiver/108237663610634862

You should NOT just take whatever HTML is in the 'content', and put it in the web-browser to view it.

You have to sanitize it. Or, render (unsafe) HTML to (safe) HTML.

Previews in ActivityPub / ActivityStreams is what should bind the disparate software and user-experiences on the Fediverse.

Not the ActivityStreams 'Note'.

Previews using 'icon', 'image', 'name', 'summary', etc.

Turns out Mastodon implements the FEP-8fcf specification (Followers collection synchronization across servers), but it expected all followers to be in a single page collection. When followers were split across multiple pages, it would only see the first page and incorrectly remove all followers from subsequent pages!

This explains so much about the strange behavior I've been seeing with #Hollo and other #Fedify-based servers over the past few months. Some people would follow me from large instances, then mysteriously unfollow later without any action on their part.

Thankfully this fix has been marked for backporting, so it should appear in an upcoming patch release rather than waiting for the next major version. Great news for all of us building on #ActivityPub!

This is why I love open source—we can identify, understand, and fix these kinds of interoperability issues together. 😊

I think it would be better for the Fediverse if back-end servers and front-end clients were not only decoupled, but separate projects.

People being able to have a service acting on their behalf as (at least part of) the back-end could be a path towards this back-end / front-end decoupling and separation.

In fact, it is an old idea. I remember ideas like this floating around in the 1990s. Including in the P2P scene.

(It is common for ideas to get rediscovered over and over and over again. Different people trying to solve similar problems, and independently coming up with similar solutions.)

In many ways, I like the basic idea of ActivityPods, Bluesky PDS, Account Abstraction.

A service acting on your behalf, and in many ways representing you (the user), with other software.

And something to which data gets "attached".

Coming soon in #Fedify 1.5.0: Smart fan-out for efficient activity delivery!

After getting feedback about our queue design, we're excited to introduce a significant improvement for accounts with large follower counts.

As we discussed in our previous post, Fedify currently creates separate queue messages for each recipient. While this approach offers excellent reliability and individual retry capabilities, it causes performance issues when sending activities to thousands of followers.

Our solution? A new two-stage “fan-out” approach:

1. When you call Context.sendActivity(), we'll now enqueue just one consolidated message containing your activity payload and recipient list
2. A background worker then processes this message and re-enqueues individual delivery tasks

The benefits are substantial:

• Context.sendActivity() returns almost instantly, even for massive follower counts
• Memory usage is dramatically reduced by avoiding payload duplication
• UI responsiveness improves since web requests complete quickly
• The same reliability for individual deliveries is maintained

For developers with specific needs, we're adding a fanout option with three settings:

• "auto" (default): Uses fanout for large recipient lists, direct delivery for small ones
• "skip": Bypasses fanout when you need different payload per recipient
• "force": Always uses fanout even with few recipients

// Example with custom fanout setting
await ctx.sendActivity(
  { identifier: "alice" },
  recipients,
  activity,
  { fanout: "skip" }  // Directly enqueues individual messages
);

This change represents months of performance testing and should make Fedify work beautifully even for extremely popular accounts!

For more details, check out our docs.

What other #performance optimizations would you like to see in future Fedify releases?

#ActivityPub #fedidev

We'd like to introduce the #Fedify project family—a set of related tools that make building #ActivityPub applications more accessible:

Fedify

Fedify (@fedify) is a #TypeScript library for building federated server applications powered by ActivityPub and other #fediverse standards. It provides type-safe objects for Activity Vocabulary, WebFinger client/server, HTTP Signatures, and more—eliminating boilerplate code so you can focus on your application logic.

Hollo

Hollo (@hollo) is a single-user microblogging server powered by Fedify. While designed for individual users, it's fully federated through ActivityPub, allowing interaction with users across the fediverse. #Hollo implements Mastodon-compatible APIs, making it compatible with most Mastodon clients without needing its own web interface.

Hollo also serves as our testing ground for bleeding-edge Fedify features before they're officially released.

BotKit

BotKit (@botkit) is our newest family member—a framework specifically designed for creating ActivityPub bots. Unlike traditional Mastodon bots, #BotKit creates standalone ActivityPub servers that aren't constrained by platform-specific limitations (like character counts).

BotKit's API is intentionally simple—you can create a complete bot in a single TypeScript file!

All three projects are open source and hosted under the @fedify-dev GitHub organization. While they serve different purposes, they share common goals: making ActivityPub development more accessible and expanding the fediverse ecosystem.

What about the Fediverse or Mastodon, etc, frustrates you or confuses you?

#DeSo #FediDev #FediDevs #Fediverse #FediverseUX #FediUX #Mastodon

Got an interesting question today about #Fedify's outgoing #queue design!

Some users noticed we create separate queue messages for each recipient inbox rather than queuing a single message and handling the splitting later. There's a good reason for this approach.

In the #fediverse, server response times vary dramatically—some respond quickly, others slowly, and some might be temporarily down. If we processed deliveries in a single task, the entire batch would be held up by the slowest server in the group.

By creating individual queue items for each recipient:

• Fast servers get messages delivered promptly
• Slow servers don't delay delivery to others
• Failed deliveries can be retried independently
• Your UI remains responsive while deliveries happen in the background

It's a classic trade-off: we generate more queue messages, but gain better resilience and user experience in return.

This is particularly important in federated networks where server behavior is unpredictable and outside our control. We'd rather optimize for making sure your posts reach their destinations as quickly as possible!

What other aspects of Fedify's design would you like to hear about? Let us know!

• Slow servers don't delay delivery to others
• Failed deliveries can be retried independently
• Your UI remains responsive while deliveries happen in the background

It's a classic trade-off: we generate more queue messages, but gain better resilience and user experience in return.

This is particularly important in federated networks where server behavior is unpredictable and outside our control. We'd rather optimize for making sure your posts reach their destinations as quickly as possible!

#ActivityPub #fedidev

Coming soon in #Fedify 1.5.0: Smart fan-out for efficient activity delivery!

After getting feedback about our queue design, we're excited to introduce a significant improvement for accounts with large follower counts.

As we discussed in our previous post, Fedify currently creates separate queue messages for each recipient. While this approach offers excellent reliability and individual retry capabilities, it causes performance issues when sending activities to thousands of followers.

Our solution? A new two-stage “fan-out” approach:

1. When you call Context.sendActivity(), we'll now enqueue just one consolidated message containing your activity payload and recipient list
2. A background worker then processes this message and re-enqueues individual delivery tasks

The benefits are substantial:

• Context.sendActivity() returns almost instantly, even for massive follower counts
• Memory usage is dramatically reduced by avoiding payload duplication
• UI responsiveness improves since web requests complete quickly
• The same reliability for individual deliveries is maintained

For developers with specific needs, we're adding a fanout option with three settings:

• "auto" (default): Uses fanout for large recipient lists, direct delivery for small ones
• "skip": Bypasses fanout when you need different payload per recipient
• "force": Always uses fanout even with few recipients

// Example with custom fanout setting
await ctx.sendActivity(
  { identifier: "alice" },
  recipients,
  activity,
  { fanout: "skip" }  // Directly enqueues individual messages
);

This change represents months of performance testing and should make Fedify work beautifully even for extremely popular accounts!

#ActivityPub #fedidev

Got an interesting question today about #Fedify's outgoing #queue design!

Some users noticed we create separate queue messages for each recipient inbox rather than queuing a single message and handling the splitting later. There's a good reason for this approach.

In the #fediverse, server response times vary dramatically—some respond quickly, others slowly, and some might be temporarily down. If we processed deliveries in a single task, the entire batch would be held up by the slowest server in the group.

By creating individual queue items for each recipient:

• Fast servers get messages delivered promptly
• Slow servers don't delay delivery to others
• Failed deliveries can be retried independently
• Your UI remains responsive while deliveries happen in the background

It's a classic trade-off: we generate more queue messages, but gain better resilience and user experience in return.

This is particularly important in federated networks where server behavior is unpredictable and outside our control. We'd rather optimize for making sure your posts reach their destinations as quickly as possible!

#ActivityPub #fedidev

We'd like to introduce the #Fedify project family—a set of related tools that make building #ActivityPub applications more accessible:

Fedify

Fedify (@fedify) is a #TypeScript library for building federated server applications powered by ActivityPub and other #fediverse standards. It provides type-safe objects for Activity Vocabulary, WebFinger client/server, HTTP Signatures, and more—eliminating boilerplate code so you can focus on your application logic.

Hollo

Hollo (@hollo) is a single-user microblogging server powered by Fedify. While designed for individual users, it's fully federated through ActivityPub, allowing interaction with users across the fediverse. #Hollo implements Mastodon-compatible APIs, making it compatible with most Mastodon clients without needing its own web interface.

Hollo also serves as our testing ground for bleeding-edge Fedify features before they're officially released.

BotKit

BotKit (@botkit) is our newest family member—a framework specifically designed for creating ActivityPub bots. Unlike traditional Mastodon bots, #BotKit creates standalone ActivityPub servers that aren't constrained by platform-specific limitations (like character counts).

BotKit's API is intentionally simple—you can create a complete bot in a single TypeScript file!

All three projects are open source and hosted under the @fedify-dev GitHub organization. While they serve different purposes, they share common goals: making ActivityPub development more accessible and expanding the fediverse ecosystem.

Fedifyの関連プロジェクトをご紹介したいと思います。ActivityPubアプリケーション開発をより簡単にするツール群です：

Fedify

Fedify（@fedify）はActivityPubやその他のフェディバース標準を活用する連合型サーバーアプリケーションを構築するためのTypeScriptライブラリです。Activity Vocabularyの型安全なオブジェクト、WebFingerクライアント・サーバー、HTTP Signaturesなどを提供し、ボイラープレートコードを削減してアプリケーションロジックに集中できるようにします。

Hollo

Hollo（@hollo）はFedifyで動作するお一人様用マイクロブログサーバーです。個人向けに設計されていますが、ActivityPubを通じて完全に連合化されており、フェディバース全体のユーザーと交流することができます。HolloはMastodon互換APIを実装しているため、独自のウェブインターフェースがなくても、ほとんどのMastodonクライアントと互換性があります。

Holloはまた、正式リリース前の最新Fedify機能をテストする実験場としても活用されています。

BotKit

BotKit（@botkit）は私たちの最も新しいメンバーで、ActivityPubボットを作成するために特別に設計されたフレームワークです。従来のMastodonボットとは異なり、BotKitはプラットフォーム固有の制限（文字数制限など）に縛られない独立したActivityPubサーバーを作成します。

BotKitのAPIは意図的にシンプルに設計されており、単一のTypeScriptファイルで完全なボットを作成できます！

これら三つのプロジェクトはすべて@fedify-dev GitHubオーガニゼーションでオープンソースとして公開されています。それぞれ異なる目的を持っていますが、ActivityPub開発をより身近にし、フェディバースのエコシステムを拡大するという共通の目標を共有しています。

これら三つのプロジェクトはすべて@fedify-dev GitHubオーガニゼーションでオープンソースとして公開されています。それぞれ異なる目的を持っていますが、ActivityPub開発をより身近にし、フェディバースのエコシステムを拡大するという共通の目標を共有しています。

これらのプロジェクトを試してみたり、開発に貢献したりすることに興味がある場合は、以下をご覧ください：

#Fedify #ActivityPub #フェディバース #fediverse #Hollo #BotKit #fedidev

#Fedify 자매 프로젝트들을 소개해 드리고자 합니다. #ActivityPub 애플리케이션 개발을 더 쉽게 만들어주는 관련 도구들입니다:

Fedify

Fedify(@fedify)는 ActivityPub와 다른 #연합우주(#fediverse) 표준을 기반으로 연합 서버 애플리케이션을 구축하기 위한 #TypeScript 라이브러리입니다. Activity Vocabulary를 위한 타입 안전한 객체, WebFinger 클라이언트·서버, HTTP Signatures 등를 제공하여 반복적인 코드를 줄이고 애플리케이션 로직에 집중할 수 있게 해줍니다.

Hollo

Hollo(@hollo)는 Fedify로 구동되는 1인 사용자용 마이크로블로깅 서버입니다. 1인 사용자를 위해 설계되었지만, ActivityPub를 통해 완전히 연합되어 연합우주 전체의 사용자들과 상호작용할 수 있습니다. Hollo는 Mastodon 호환 API를 구현하여 자체 웹 인터페이스 없이도 대부분의 Mastodon 클라이언트와 호환됩니다.

Hollo는 또한 정식 출시 전에 최신 Fedify 기능을 테스트하는 실험장으로도 활용되고 있습니다.

BotKit

BotKit(@botkit)은 저희의 가장 새로운 구성원으로, ActivityPub 봇을 만들기 위해 특별히 설계된 프레임워크입니다. 전통적인 Mastodon 봇과 달리, BotKit은 플랫폼별 제한(글자 수 제한 등)에 구애받지 않는 독립적인 ActivityPub 서버를 만듭니다.

BotKit의 API는 의도적으로 단순하게 설계되어 단일 TypeScript 파일로 완전한 봇을 만들 수 있습니다!

세 프로젝트 모두 @fedify-dev GitHub 조직에서 오픈 소스로 공개되어 있습니다. 각기 다른 목적을 가지고 있지만, ActivityPub 개발을 더 접근하기 쉽게 만들고 연합우주 생태계를 확장한다는 공통된 목표를 공유합니다.

이러한 프로젝트를 사용해보거나 개발에 기여하는 데 관심이 있으시다면, 다음을 확인해보세요:

#fedidev #Hollo #BotKit

We'd like to introduce the #Fedify project family—a set of related tools that make building #ActivityPub applications more accessible:

Fedify

Fedify (@fedify) is a #TypeScript library for building federated server applications powered by ActivityPub and other #fediverse standards. It provides type-safe objects for Activity Vocabulary, WebFinger client/server, HTTP Signatures, and more—eliminating boilerplate code so you can focus on your application logic.

Hollo

Hollo (@hollo) is a single-user microblogging server powered by Fedify. While designed for individual users, it's fully federated through ActivityPub, allowing interaction with users across the fediverse. #Hollo implements Mastodon-compatible APIs, making it compatible with most Mastodon clients without needing its own web interface.

Hollo also serves as our testing ground for bleeding-edge Fedify features before they're officially released.

BotKit

BotKit (@botkit) is our newest family member—a framework specifically designed for creating ActivityPub bots. Unlike traditional Mastodon bots, #BotKit creates standalone ActivityPub servers that aren't constrained by platform-specific limitations (like character counts).

BotKit's API is intentionally simple—you can create a complete bot in a single TypeScript file!

All three projects are open source and hosted under the @fedify-dev GitHub organization. While they serve different purposes, they share common goals: making ActivityPub development more accessible and expanding the fediverse ecosystem.
