Open-source startups in Backend platforms
Batteries-included backends that bundle database, auth and storage so an app can ship without one. 11 open-source startups in this directory are filed under Backend platforms. 10 pushed code within 30 days of the snapshot of 2026-09-22, 1 has been quiet for 31–120 days, 0 have not pushed in over 120 days. The category is chosen by Jev, TypeSafe’s classifier, reading only the repository’s own name, description and homepage — one category per project, so something that spans two appears under whichever the classifier judged closest.

The list
All 11, 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. The “built for” column and the “alternative to” chips are Jev’s answers about the same repository description, published with the rest of them.
