CommonPub
An open ActivityPub federation protocol and platform for self-hosted maker communities.
For Makers
Document your builds with rich block editors. Parts lists, wiring diagrams, build steps, and code blocks, everything you need to share how you built it.
Community Hubs
Create spaces for your community, product, or company. Discussions, content galleries, learning paths, and contests, all in one place.
Federated
Built on ActivityPub. Your instance, your data. Follow makers across instances. No single point of failure, no platform lock-in.
Learning Paths
Structured learning with modules, lessons, quizzes, and certificates. Track your progress and earn credentials.
Contests
Run build contests with prizes, judges, and community voting. From small jams to sponsored competitions.
Self-Hosted
Deploy with Docker. PostgreSQL, Redis, and your choice of S3-compatible storage. Full control over your data.
