Firebase alternatives: 9 apps ranked by verified data

Facts checked Oct 25, 2026AppBreakup editorialHow we rank

Common reasons people leave Firebase: ties your app closely to Google Cloud, and noSQL query limits often force data duplication. We ranked 9 alternatives by how directly each one replaces Firebase, then by reviews, real visits and how recently each app's facts were checked against its own website. Supabase currently ranks first.

    score / 100

    Why switch from Firebase

    Relational Postgres instead of NoSQL, open source, and a similar all-in-one dashboard.

    Pros

    • Auth, storage, realtime and functions in one dashboard
    • Open source and self-hostable with Docker
    • Large community and many framework guides

    Cons

    • Free projects pause after a week of inactivity
    • Usage charges for compute and egress can be hard to predict
    • Self-hosting the full stack takes real operations work
