Compass / Open-source directory
The open-source directory.
64 projects, model families and foundations, each with the place where its people talk. Pick one that matters to your work and join it: read the forum for a week, then answer a question.
11 of them run in this workshop and are marked. 4 carry a licence that restricts use or are closed products (AutoGPT, Dify, LM Studio, n8n), and their entries say so. Every link was opened on 7 October 2026.

How to use this page
Choose one project from a category you work in. Open its community link and read for a few days before posting. The fastest way in is to answer a question someone else asked, or to fix one line of documentation.
To build with other people from this workshop, join the Telegram group, opens in a new tab.
How the list is kept
Stars and licences are read from GitHub by a script, last on 7 October 2026. Community links are opened by hand on the same day, and Discord invites are checked against Discord itself, because a dead invite still loads a page.
