Firebase is Google’s app development platform: a realtime database, auth, storage, hosting, cloud functions, messaging and analytics behind one SDK.
Catalog categories: developer_tool.
Catalogued capability areas: - Realtime/firestore database and offline sync - Authentication, file storage, hosting - Cloud functions, push messaging, analytics
This summary reflects the catalog record, not a complete product specification. Verify intended users, end-to-end workflows, supported platforms, edge cases, data handling, and constraints against cited sources. Treat capability labels as research leads until that verification is complete.
4 candidate projects in the landscape. A candidate may cover all, part, or none of what Firebase does — read the coverage and gaps below.
Postgres-based backend with auth, storage, realtime, functions.
Closest drop-in in scope.
Self-hostable backend: auth, database, storage, functions.
Feature-complete alternative.
Single-binary backend with realtime and auth.
Small and embeddable.
Open app backend (the original Firebase competitor).
Mature, self-hosted.
Alternative coverage
Available. Multiple mature, self-hostable backends cover the core.
The gap
Firebase’s managed scale, its proprietary SDK surface and vendor-hosted extensions have no single open equivalent.
This Markdown file is the coding-agent skill for Firebase. Give it to your agent in your project; it guides research, reuse decisions, implementation and verification.
Give the Firebase skill to your coding agent in your project. Ask it to evaluate Supabase ↗ against your needs, reuse what fits, then follow the skill's build and verification instructions.
Give the product skill to your coding agent in the project where you want to build. Optional starter workspace: rae build product google-firebase --out ./google-firebase. CLI reference.
