Frequently asked questions
How many open source claude projects are there?
This registry tracks 150 projects tagged claude, with 2,405,028 GitHub stars between them. The most-adopted is ECC at 294,916 stars.
Are these claude projects free to use?
Yes — 144 of the 150 carry an explicit open-source licence across 4 distinct licences, so there is no licence fee. Where a project also sells a hosted or enterprise version, the self-hosted path remains free.
Which claude project should I choose?
The list above is ranked by GitHub stars, but stars measure attention rather than fit. Check three things on each card: the licence (permissive versus copyleft), the language it is written in, and the last-push date — a high-star project that has not been pushed in a year is a liability.
Are these claude projects still maintained?
133 of the 150 were pushed in the last 90 days, and every card shows its exact last-push date so you can see the rest. Sort your shortlist by that date before committing to a migration.
