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.
Learning Paths
Structured learning with modules, lessons, quizzes, and certificates. Track your progress and earn credentials.
Self-Hosted
Deploy with Docker. PostgreSQL, Redis, and your choice of S3-compatible storage. Full control over your data.
