Alternative to
Open-source alternatives to Firebase that still ship
9 open-source startups in this directory are positioned against Firebase. 9 pushed code within 30 days of the snapshot of 2026-09-22, 0 have been quiet for 31–120 days, 0 have not pushed in over 120 days. “Alternative to Firebase” is a judgment by Jev, TypeSafe’s classifier, made from the repository’s own name, description and homepage, and printed only when it put that match at 0.5 or better. It is not a claim these projects make about themselves, it is not a feature comparison, and Firebase has nothing to do with this page.

The list
All 9, most-starred first.
The last column is the most recent push GitHub reported to us on 2026-09-22. It counts a push to any branch, by a person or a bot — it is not a claim that anyone is maintaining the project, and a quiet repository may be a finished one.
