Fedify: ActivityPub server framework
@fedify@hollo.social
We're excited to announce that #Fedify has been awarded a service agreement by the @sovtechfund! The Sovereign Tech Fund is investing €192,000 in Fedify's development over 2025–2026 to strengthen the fediverse ecosystem.
This investment will enable us to significantly expand Fedify's capabilities and make it easier for developers to build federated applications. The commissioned work focuses on improving developer experience, adding comprehensive debugging tools, and ensuring Fedify remains at the forefront of #ActivityPub innovation.
Here are the key milestones we'll be delivering:
-
Web framework integrations: Official adapters for Next.js, Elysia, Fastify, and Koa, making it seamless to add federation to existing applications
-
ActivityPub debug & development tools: Real-time debug dashboard with WebSocket monitoring, federation lifecycle hooks, and implementation checklist CLI to make federation interactions transparent and debuggable
-
Storage & infrastructure enhancements:
SQLiteKvStorefor robust file-based storage across Node.js, Deno, and Bun, plus performance optimizations for production deployments -
Comprehensive documentation & examples: Specialized tutorials for building federated blogs, social networks, and content platforms, with complete working examples and migration guides
-
Observability & monitoring: Full OpenTelemetry metrics, performance benchmarking tools, and federation health dashboards for production environments
-
Advanced features & standards: FEP-ef61 (Portable Objects) support and implementation of emerging Fediverse Enhancement Proposals to keep Fedify at the cutting edge
All developments will be open source and available for the entire #fediverse community to use, contribute to, and build upon.
