Firebase alternatives

Five backends to compare if Firebase’s usage costs, proprietary services or operational fit no longer suit your app.

Firebase is a managed backend platform for web and mobile apps, with services such as authentication and notifications. Its free plan lowers the cost of starting, but usage-based billing and proprietary services can shape a later migration. The alternatives below take different paths: Supabase and Appwrite are open source and self-hostable; Convex is a hosted TypeScript backend; Xano focuses on managed API building; PlayFab is built for games. Compare them against your data model, workload and hosting requirements.

01Why people leave Firebase

Usage costs change with demand

Firebase’s usage-based bills can make costs harder to forecast as an app grows. Model expected traffic and service use before choosing another backend; a free plan does not establish your eventual bill.

Reliability concerns in production

One long-running Reddit thread reports reliability and scalability problems with Realtime Database. Other commenters describe Firebase as a productivity boost, so treat those reports as experience, not a guarantee of failure.

Services shape the exit plan

Firebase’s proprietary services can tie client code and data workflows to its platform. One Reddit thread also raises concern about Google product continuity; weigh that against teams that choose Firebase specifically to stay on Google Cloud.

02The alternatives, ranked by fit

  1. Best for Postgres teams

    Supabase

    Supabase is a practical choice if you want a Postgres-backed BaaS rather than Firebase’s proprietary services. It is open source and self-hostable, with built-in Auth for small apps. The pricing page lists a free plan and a $25 starting price. Plan for a data and client migration, and model usage costs against your workload before moving.

    Trade-off: Postgres changes the data model, and usage costs still need planning.

  2. Best for self-hosting

    Appwrite

    Appwrite suits teams looking for a broad backend stack with a self-hosting path. It is open source, and the product supports both Cloud and self-hosting. The pricing page lists a free plan, with the starting price shown as n/a. Before migrating, check resource limits and validate function behavior against your app’s workflows.

    Trade-off: Budget around resource limits and verify function behavior.

  3. Best for TypeScript apps

    Convex

    Convex is aimed at TypeScript apps with live data and teams consolidating backend services. That makes it worth comparing if reactive app behavior is central to your Firebase use. The pricing page lists a free plan and a $25 starting price. Convex is hosted, so account for service lock-in, usage costs and the work of moving existing data and client code.

    Trade-off: Hosted-service lock-in and usage costs remain.

  4. Best for API workflows

    Xano

    Xano focuses on API building, managed backend operations, and governed builds and releases. It is self-hostable and is positioned for business apps and teams building APIs with AI agents. The pricing page lists a free plan and an $85 starting price. Compare its workflow and release model with your current Firebase services before planning the migration.

    Trade-off: The listed starting price is higher than the other options here.

  5. Best for live games

    PlayFab

    PlayFab is the most focused alternative here for cross-platform live games, with Azure-backed game services, LiveOps and analytics. The pricing page lists a free plan and a $0 starting price, but costs are metered. Its core services have no self-hosting path, so it does not remove hosted-provider dependence.

    Trade-off: Metered costs and no self-hosting for core services.

Questions people ask

What are some open-source alternatives to Firebase?

Supabase and Appwrite are the open-source options in this comparison, and both are self-hostable. Supabase is Postgres-backed and includes Auth; Appwrite offers a broader backend stack with Cloud and self-hosting. Check each project’s current licence and service limits before adopting it; open source alone does not make a migration straightforward.

Is Google shutting down Firebase Studio?

A Firebase Studio status announcement should not be read as a Firebase shutdown announcement unless Google explicitly says so. Check Google’s current product announcements for Firebase Studio before changing a dependency. For production planning, assess the status and support of the specific Firebase services your app uses.

Which is best, Supabase or Firebase?

There is no universal winner. Supabase is a better fit to evaluate if you want Postgres, an open-source option or self-hosting. Firebase may fit teams that value managed Auth and Google Cloud alignment. For Firestore versus Realtime Database, compare your app’s data model and access patterns, then account for migration work and usage costs.
