# Firebase

> Google's app platform: Firestore documents, auth, functions, deep mobile SDKs.

- The original realtime backend, still the most operationally proven
- Firestore is a document store with live listeners and genuine offline persistence
- Best mobile SDKs on this list; access control is a proprietary per-document rules language
- Nothing self-hostable, no SQL, and the export format reads only in Firestore's own importer

| Agent fit | 2 | Inferred | - | - | Untyped documents, console-configured indexes and a string rules DSL give an agent very little to check itself against. | https://toolweight.com/compare/convex-alternatives#firebase--agent_fit |

**Verdict.** Best offline story and mobile SDKs, worst exit on the page; fine only if you never migrate.
