Frequently asked questions

How many open source kubernetes projects are there?

This registry tracks 77 projects tagged kubernetes, with 747,554 GitHub stars between them. The most-adopted is NetData at 80,561 stars.

Are these kubernetes projects free to use?

Yes — 72 of the 77 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 kubernetes 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 kubernetes projects still maintained?

72 of the 77 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.
