Replacement guide

How do I replace Firebase?

4 open source alternatives that can cover different use cases of Firebase — each with its real fit, not a "replaces it completely" promise.

Can replace Firebase for database, authentication, file storage and realtime subscriptions, on top of standard PostgreSQL.

Limitation: The full self-hosted stack has quite a few internal services to maintain.

Can replace Firebase for authentication, database, storage and serverless functions, with SDKs for Flutter, Swift, Android and Web.

Limitation: Stack with several internal containers, heavier to audit than a single-binary alternative.

Can replace Firebase for authentication, database and storage on small-to-medium projects, all in a single binary.

Limitation: Uses SQLite, which limits horizontal scalability at high volume.

Can replace Firebase's instant API layer (GraphQL/REST over your database, with row-level permissions) if you already use or plan to use PostgreSQL.

Limitation: Doesn't include authentication or file storage like Firebase — it only covers the data-access layer.

Already know which one you want?

Add them to the Stack Builder and generate a docker-compose.yml ready to deploy, alone or with the rest of your stack.
