#ActivityPub

I think I’ve found a relatively nice solution for #FediLinks in #Conversations_im.

You can put web+ap URIs into a message (or room description) and ideally a click on those will open your Mastodon client. However if no installed app supports those (the only app that I’m aware of is Fedilab) Conversations will open a browser instead.

Currently no app will create web+ap links but it is fairly easy to handcraft them.

Pixelfed before v0.12.5 has a vulnerability where it could leak your private posts, regardless of whether you are a Pixelfed user or not.
Admins should update ASAP.

When following someone from a different server on the Fediverse, the remote server decides whether you are allowed to do that. This enables features like locked accounts. Due to an implementation mistake, Pixelfed ignores this and allows anyone to follow even private accounts on other servers. If a legitimate user from a Pixelfed instance follows you on your locked account, anyone on that Pixelfed instance can read your private posts.

I wrote a blog post about how I found the vulnerability, how disclosure coordination went and general ramblings about Fediverse safety:

Hollo

@hollo@hollo.social

Holloを紹介します！

Holloは、個人向けの連合型マイクロブログソフトウェアです。FedifyとBunを基盤に構築され、ActivityPubプロトコルを通じて他のインスタンスやサービスと連携することができます。

Holloの特徴は、一人のユーザーのために設計された専用のインスタンスという点です。これにより、ユーザーは自分だけのスペースを持ちながら、Mastodon、Misskey、その他のActivityPub対応サービスのユーザーとも交流できます。

独自のウェブインターフェースを持たない代わりに、MastodonのAPIと互換性があるため、既存の多くのMastodonクライアントアプリを使用してHolloにアクセスできます。これにより、使い慣れたインターフェースでHolloを利用することができます。

主な機能には、投稿の作成・編集・削除、返信、メディア添付、投票、お気に入り、ブックマーク、ピン留めなどがあります。また、プロフィール編集、フォロー/フォロワー管理、リスト作成なども可能です。さらに、Markdownをサポートしているため、投稿やプロフィールの書式設定が容易に行えます。

Holloは現在開発の初期段階にあり、継続的に機能の追加や改善が行われています。Bunを使用することで、高速なパフォーマンスと効率的な開発が実現されています。オープンソースプロジェクトとして、GitHubで公開されており、コミュニティからの貢献を歓迎しています。

個人のブログとソーシャルメディアの利点を組み合わせたHolloは、プライバシーを重視しながら、より広いコミュニティとのつながりを求める人々に適したプラットフォームとなっています。

Fedify: an ActivityPub server framework

@fedify@hollo.social

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:

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

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.

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

ALT text details

sharedInbox An optional endpoint used for wide delivery of publicly addressed activities and activities sent to followers. sharedInbox endpoints SHOULD also be publicly readable OrderedCollection objects containing objects addressed to the Public special collection. Reading from the sharedInbox endpoint MUST NOT present objects which are not addressed to the Public endpoint.

@reiver ⊼ (Charles)

@reiver@mastodon.social

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.

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.

Open Risk

@openrisk@mastodon.social

Thinking about internet protocols like #activitypub or #atproto as just "social media", namely platforms for sharing cat images, influencers and followers, shitposting and memes, trolls and flamewars etc. is missing the point entirely.

These are merely emergent behaviors when people interact with primitive forms of "digital society".

In truth these are "societal media", they increasingly capture a good fraction of human reality. The masters of #surveillancecapitalism know this all too well.

@fedify@hollo.social

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

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

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

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

Enhanced Key Format Compatibility

Improved Key Selection Logic

New Authorization Options

Efficient Bulk Message Queueing

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

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!

Linux Is Best

A reminder, the Fediverse cost money.

Yes, it is free for YOU to use, but your local administrator pays for domain registration, web hosting, storage space, CDN, and of course, bandwidth.

The busier and more active your Fedi site, the most it cost.

If you are able, consider reaching out to your admin, and asking how you can help. Even small contributions add up and make a difference.

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.

Scott Laird

@laird@hachyderm.io

I'm looking for a new comment system for my #Hugo blog, and I'm not seeing any clearly great options.

I've been using #Commento for #comments on my blog for a few years now, and it's about time to switch comment systems.

Commento has been effectively unmaintained for 4 years (see https://gitlab.com/commento/commento). Their (paid) hosted version has been continuing to work, but I've seen increasing numbers of errors lately, so it's time to move.

I'd really *love* something that could integrate semi-natively with #activitypub so new blog posts could show up in Mastodon and Mastodon replies would show up as comments, *but* I don't want to require a fediverse account for commenters; that rules out most (all?) of the embedded-Mastodon comment options.. After looking through Hugo's somewhat-outdated list of commenting options (https://gohugo.io/content-management/comments/), it looks like #Discourse is the only option that even *slightly* fits that, and it's a lot heavier-weight than I really want to run today. Hours-of-maintenance-per-comment should be less than 1, thanks.

Basic requirements:

- Either easy to self-host or has a cheap hosted option.
- Allows anonymous comments plus common external auth options.
- Possible to import comments from Commento, possibly requiring code on my part, but it needs to allow arbitrary names, etc.
- Works with static sites.
- Not a privacy disaster
- If self-hosted, ideally written in something sane -- Go, Rust, etc. *Ideally* it's a single binary that listens to HTTP and stores comments in Postgres.
- Supports Markdown.

Does anyone have anything that they're really happy with?

Fedify: an ActivityPub server framework

@fedify@hollo.social

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

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

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

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

Enhanced Key Format Compatibility

Fedify: an ActivityPub server framework

@fedify@hollo.social

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

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

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

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

This is the kind of innovation that #ActivityPub and the #Fediverse allows. I just learnt about #Bandwagon (through a post by @atomicpoet) which is a #music artist site (not unlike #Bandcamp). Artists and their posts can be followed just like anyone on the Fediverse.

It's a little rudimentary at the moment (both in style and functionality), and I don't think there is a way to purchase albums for download, but it is a nice example of what is possible.

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.

One month has passed since I am using #selfhosted #activitypub instance 🎉. I have linux #docker compose stack with @mitra backend (#rust/#postgresql) written by @silverpill and @phanpy as my daily UI for desktop and mobile. Everything works fluent, backend memory print is really low and disk usage is about 2.3 GB as I have set data retention limit to one week and it is totally enough. I am following directly around 150 users + following 7 hashtags via https://relay.fedi.buzz/ which brings also optimal amount of federated posts into my server. Highly recommended!

Is there any #ActivityPub / #Mastodon URI scheme used in the wild that would allow me to open an ActivityPub account directly in my Android app?

I've seen 'acct' and 'web+ap' mentioned but none seem to be implemented.

The goal is that given a text of "Here is my Mastodon profile acct:daniel@gultsch.social" #Conversations_im can link that directly into #Tusky. (Just like mailto and xmpp URIs open my E-Mail or IM app respectively)

Have @apps or @Tusky considered that? If not way not?

Good morning Fedi friends!

I just added a new link to my Mastodon profile: @elena 🤗

How many #ActivityPub profiles do I have now? I don't want to know 😆

Off I go continue writing about #PeerTube for #TheFutureIsFederated (part 2, showing what it's like to use the software from the POV of a creator). I look forward to doing some tests and seeing what it's like to embed PeerTube videos on my website. Article coming tomorrow.

Wishing you all a lovely day!

What is the standard method of specifying primary language of a post in #ActivityPub?

Mastodon and Hollo add contentMap.[languageCode] to object. But Pleroma and Misskey don't.
And what if there are multiple keys in contentMap?

I'm being driven up a wall by a Heisenbug I have with the #GoActivityPub HTTP-Signature plumbing.

On a multi tenant #ActivityPub service where I have two Actors, one of them can interact with the Fediverse at large without any issue, while the other gets HTTP Signature validation errors for every request.

There's no suspicious difference between the two private/public key pairs of the two actors. (I've even tried using the same key pair)

Sigh...

Pixelfed before v0.12.5 has a vulnerability where it could leak your private posts, regardless of whether you are a Pixelfed user or not.
Admins should update ASAP.

@dansup The follower approval feature itself in #activitypub is the vulnerability. It is wrong to give users the expectation that their social media posts are private. Also, approving followers reminds me of DRM on mp3 files. What are we doing?

洪民憙 (Hong Minhee)

@hongminhee@hollo.social

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.

Oh, great. #Pixelfed had a broken implementation of "follower-only" posts, _and_ fucked up the disclosure / bugfix release process.

https://fokus.cool/2025/03/25/pixelfed-vulnerability.html

Summary of the bug: If you have a protected account (on Pixelfed, Mastodon, GTS, whatever) and a Pixelfed user followed you and got approved by you, _all_ users on that instance were now able to see your followers-only posts, not just the one you approved.

A reminder, the Fediverse cost money.

Yes, it is free for YOU to use, but your local administrator pays for domain registration, web hosting, storage space, CDN, and of course, bandwidth.

The busier and more active your Fedi site, the most it cost.

If you are able, consider reaching out to your admin, and asking how you can help. Even small contributions add up and make a difference.

What I'd really like to see is BlueSky modifying their AT protocol to allow AT relays to treat ActivityPub servers as Personal Data Servers. Maybe by using aspects of the Solid protocol, as demonstrated by @activitypods?

No idea if this is technically viable, I'm just thinking out loud here. But just imagine unifying the efforts of AP, Solid and AT developer ...

Hello, I'm an open source software engineer in my late 30s living in #Seoul, #Korea, and an avid advocate of #FLOSS and the #fediverse.

I'm the creator of @fedify, an #ActivityPub server framework in #TypeScript, @hollo, an ActivityPub-enabled microblogging software for single users, and @botkit, a simple ActivityPub bot framework.

Thor A. Hopland

@hopland@snabelen.no

I always gush about @ZLabe and his account, because for one thing it makes the data he works with more accessible (via #ActivityPub), but secondly because the #infographics he stares are very informative - and consistent.

Are there any other #science, #edutainment and #infographic accounts on the #fediverse that has similar consistent and qualify of posts? Think content that is fairly easily digestible during a scroll.

We're looking for the accounts that #TeachTheFediverse.

Llevaba tiempo preguntándome si sería posible integrar el protocolo #ActivityPub (el fedi) en los #PDS (Personal Data Server) de #ATProto (el protocolo que usa #BlueSky y potencialmente otras redes futuras) y he dado con este artículo.

https://berjon.com/ap-at/

En resumen: aún no, pero sí podría ser posible en un futuro.
Honestamente, si existe una posibilidad de que ambos protocolos lleguen a converger, se debería apostar por ello. Internet ya está demasiado fragmentada.

Newsletter platform #Ghost, an open source competitor to #Substack, is now connected to the fediverse, also known as the open social web.

Federated apps run on the protocol #ActivityPub, which powers apps like Mastodon, Pixelfed, Threads, Flipboard, and others,
allowing posts published on one app to be seen and engaged with by those on other federated platforms.

Ghost said last year that it was working on an integration with ActivityPub, which would allow its publishers to share their blog posts with the broader open social web.

The company expected the integrations to go live last year. However, Ghost this week announced the launch of its social web beta, which now allows any site running on its Ghost Pro subscription to try out the new ActivityPub integration.

The beta feature is still in active development, the company notes in its help documentation, but is expected to ship in a more finalized state in the Ghost 6.0 release.

When Ghost Pro users connect their blog or newsletter to the fediverse, others across the open social web will be able to follow their account’s handle.

This handle is a combination of “@index,” representing the home page of the publication, followed by the domain name (@yoursite.com).

Ghost says users will soon be able to customize the @index part of their @index@yoursite.com handle.

Users on federated apps will then be able to follow the Ghost publisher’s posts, as well as interact with them by liking, replying, or reposting.

To help Ghost publishers also participate in the fediverse and build their readership,
Ghost also launched a social web reader.

Here, users can browse a “feed” of the short-form content shared across the fediverse, including posts from services like Mastodon and Threads.

In a separate area called the “Inbox,” Ghost users can keep up with long-form content, like articles published on Ghost or WordPress, the popular publishing platform that integrated with the fediverse in 2023.

“Think of the Inbox screen like your email inbox. When you follow other publications on the social web, new articles they publish will show up here,” Ghost’s help page explains.

“Clicking on a post will open an inline reader view, right inside Ghost,
and when you get to the end you’ll be able to like, repost or reply.”

With the integration of these two feeds into Ghost’s admin, Ghost will also now allow its publishers to directly post short-form content to the fediverse, helping them to build their reputation and following on the open social web.

Ghost’s Reader also alerts users of interactions like follows, replies, likes, and reposts in its “Notifications” section.

Plus, users can customize their Profile page to offer a preview of their social web account,
following/followers, and their content, both short and long-form.

Later, the company hopes to more deeply integrate users’ social web profiles with Ghost memberships,
but for now, they operate independently from one another.

Other coming features include tools to block, report, and mute people or add images or media to notes and replies.

Hey all, the easiest way I can find #Ghost blogs using #ActivityPub is to search for @index and you will get some Friendica results, etc, but for now, that should be a sure way to find almost all the blogs that have enabled this feature so far. I couldn't tell if replies appear as comments, so if you don't want your comments on their blog, don't reply to their fediverse posts. A few told me they can see my comments on their dashboard but I don't know what that means. #FediTips #Fediverse

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:

When you call Context.sendActivity(), we'll now enqueue just one consolidated message containing your activity payload and recipient list
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?

Flowchart comparing Fedify's current approach versus the new fan-out approach for activity delivery. The current approach shows: 1. sendActivity calls create separate messages for each recipient (marked as a response time bottleneck) 2. These individual messages are queued in outbox 3. Messages are processed independently 4. Three delivery outcomes: Recipient 1 (fast delivery), Recipient 2 (fast delivery), and Recipient 3 (slow server) The fan-out approach shows: 1. sendActivity creates a single message with multiple recipients 2. This single message is queued in fan-out queue (marked as providing quick response) 3. A background worker processes the fan-out message 4. The worker re-enqueues individual messages in outbox 5. These are then processed independently 6. Three delivery outcomes: Recipient 1 (fast delivery), Recipient 2 (fast delivery), and Recipient 3 (slow server) The diagram highlights how the fan-out approach moves the heavy processing out of the response path, providing faster API response times while maintaining the same delivery characteristics.

Fedify: an ActivityPub server framework

@fedify@hollo.social

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!

#ActivityPub #fedidev

ALT text details

A flowchart comparing two approaches to message queue design. The top half shows “Fedify's Current Approach” where a single sendActivity call creates separate messages for each recipient, which are individually queued and processed independently. This results in fast delivery to working recipients while slow servers only affect their own delivery. The bottom half shows an “Alternative Approach” where sendActivity creates a single message with multiple recipients, queued as one item, and processed sequentially. This results in all recipients waiting for each delivery to complete, with slow servers blocking everyone in the queue.

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.

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

Fedify

Hollo

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

BotKit

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

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.

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

When you call Context.sendActivity(), we'll now enqueue just one consolidated message containing your activity payload and recipient list
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?

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.

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.

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

🏕️ my adventures in #selfhosting - day 93 ✨

Thanks to the brilliant advice of @CyberSaloperie I have found an easy-to-implement, no sweat solution for my redirect issue. I am about to create a test subdomain with #YunoHost to try it out before I make the real switch (from my current Ghost blog to the new, self-hosted one).

Maybe tomorrow I'll share with you the URL of my self-hosted Ghost blog if you want to try things out? 🙈 I have already imported my existing members, I'm ready to go 🚀

And yes, I'm fully aware the timing of my switch (from a Ghost Pro plan to self-hosted) is odd, considering Ghost Pro accounts are now part of the Fediverse. It's just that I couldn't justify spending so much ($31/month) on a free, non-monetized blog that I am capable of self-hosting. It's 6x the cost of my Debian or Ubuntu VPS.

And I kept getting close to the edge of 1000 members, which would have increased my monthly payments. Now I don't have to stress out about getting new readers. From what I understand #ActivityPub followers count as members for Ghost, so someone who gets a sizable following on their federated Ghost site would have to pay more.

I'm sure many people will love this feature (it's fantastic!) but it's not for me. I already have 3 federated Wordpress blogs and too many ActivityPub profiles as it is 🙃
