Frequently asked questions

How many open source openai projects are there?

This registry tracks 64 projects tagged openai, with 1,055,958 GitHub stars between them. The most-adopted is Open WebUI at 157,575 stars.

Are these openai projects free to use?

Yes — 60 of the 64 carry an explicit open-source licence across 5 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 openai 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 openai projects still maintained?

51 of the 64 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.
