Frequently asked questions
How many open source cloud-native projects are there?
This registry tracks 70 projects tagged cloud-native, with 608,788 GitHub stars between them. The most-adopted is ClickHouse at 50,719 stars.
Are these cloud-native projects free to use?
Yes — 70 of the 70 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 cloud-native 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 cloud-native projects still maintained?
64 of the 70 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.
