Supabase on Borg App Hub Open source Give a new app a database, sign-in, and file storage on day one, without standing up servers yourself. No per-seat cost; pay for AI + compute Runs inside your Borg workspace.
Appwrite Open source Self-hosted backend APIs and authentication. Free to self-host; hosted plans available. Different APIs and data model from Firebase.
PocketBase Open source Small apps with a simple local backend. Free to self-host; hosting costs extra. You manage uptime and scale.
AWS Amplify SaaS Apps built around AWS services. Usage-based AWS service charges. Many AWS services to understand.
MongoDB Atlas SaaS Managed document databases. Free tier; paid clusters and usage. Auth and file storage need other tools.
Nhost Open source Postgres-backed app services. Self-hosting available; paid cloud plans. GraphQL-focused workflow differs from Firebase.
Parse Platform Open source Self-hosted backend APIs. Free to self-host; infrastructure costs extra. You operate the backend yourself.

The push

Why teams leave Firebase

  • Heavy read traffic drives up Blaze plan usage charges fast.

  • Firestore's document data doesn't map cleanly onto Supabase's PostgreSQL tables.

  • Some teams want to pick their own hosting region instead of Google's infrastructure.

  • Rewriting Firebase SDK calls for another backend is real migration work, not a toggle.

Before switching

Check the coverage you need

Review the feature details for Supabase before moving your workflow from Firebase.

  • App database

    Partly covered

    PostgreSQL replaces the data job, not Firestore's document API.

  • Authentication

    Partly covered

    Sign-in is available; providers and SDKs differ.

  • Realtime data

    Partly covered

    Subscriptions exist but are not Firestore listeners.

  • Server-side functions

    Partly covered

    Edge Functions require separate setup when self-hosted.

  • Client SDKs

    Partly covered

    Supabase SDKs exist; Firebase code needs changes.
