Frequently asked questions

How many open source opensource projects are there?

This registry tracks 21 projects tagged opensource, with 310,406 GitHub stars between them. The most-adopted is worldmonitor at 90,021 stars.

Are these opensource projects free to use?

Yes — 19 of the 21 carry an explicit open-source licence across 6 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 opensource 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 opensource projects still maintained?

19 of the 21 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.
