Supabase is an open-source, self-hostable backend built around Postgres, with a free plan and paid plans from $25. Its bundled services can shorten the path to an app, but developers on Reddit describe friction when access rules and business logic spread across RLS policies, database functions and server code. The alternatives below cover managed app backends, reactive TypeScript services, game infrastructure, self-hostable platforms and API-focused tools. The right replacement depends on which Supabase services your code actually uses.
01Why people leave Supabase
Business logic is split across layers
Reddit developers report that RLS policies, triggers and server-side rules can become hard to debug or maintain when business logic crosses those boundaries.
Usage costs can change the economics
A Reddit commenter cites storage egress costs as a reason to move files to R2. Check your own usage and current plan pricing before switching.
Supabase-specific services complicate exit
One Reddit user says moving Auth would force a broad password reset. Treat Auth, database policies and storage as separate migration risks.
02The alternatives, ranked by fit
- Best self-hostable option
AppwriteAppwriteAppwrite is the closest fit if you want a broad backend platform without committing everything to Supabase. It is open source and self-hostable, with a free plan; its listed starting price is n/a. That gives teams a route to run the platform themselves, but validate resource limits and function behavior before moving production workloads.
Trade-off: You take on self-hosting work and need to check resource limits and function behavior.

Freefree plan - Best for TypeScript apps
ConvexConvexConvex fits TypeScript applications that need live data and teams consolidating backend services. It is a different backend model from Supabase’s Postgres-centered approach, so expect to review data access and application logic rather than assume a drop-in database migration. The listed starting price is $25, with a free plan; usage costs and hosted-service lock-in remain considerations.
Trade-off: You give up Supabase’s Postgres-centered architecture for a hosted service with lock-in.

$25/mofree plan - Best for managed app services
FirebaseFirebaseFirebase suits small teams shipping web or mobile apps that want managed authentication and notifications, particularly in Google Cloud-oriented stacks. The listed starting price is $0 with a free plan, but usage-based bills and proprietary services affect the cost and exit plan. Moving from Supabase means accounting for those services, not just transferring database records.
Trade-off: Proprietary services and usage-based bills make portability and cost forecasting important.

Freefree plan - Best for API workflows
XanoXanoXano is aimed at teams building APIs with AI agents, business apps that need workflow tests, and teams that want managed backend operations. It is listed from $85 with a free plan and is self-hostable. Consider it when governed builds and releases matter more than keeping a Supabase-style Postgres backend; plan to adapt application integrations during the move.
Trade-off: Its listed starting price is higher, and migration means adapting integrations to a different backend.

$85/mofree plan - Best for live games
PlayFabPlayFabPlayFab is the most relevant choice when Supabase is backing a cross-platform live game and you need built-in LiveOps and analytics. It is a hosted, Azure-backed game backend, listed from $0 with a free plan. This is a move toward game-specific services, not a general-purpose Postgres replacement, so scope the migration around game backend features.
Trade-off: Core services have no self-hosting path, and metered costs need review.

Questions people ask
Which Supabase alternative can I self-host?
Appwrite is open source and self-hostable. Xano is also listed as self-hostable. Supabase itself is open source and self-hostable, so changing platforms is not automatically a way to reduce operational work; compare what you will need to run and maintain.
Which alternative is closest to Supabase’s Postgres model?
None of these picks is identified as a Postgres-backed replacement. Appwrite is a broad backend platform, while Convex targets TypeScript apps with live data. If keeping Postgres is a requirement, confirm the database model and migration path with each vendor before committing.
How do I estimate the cost of leaving Supabase?
Start with current database, storage and service usage, then compare it with each vendor’s plan and metered charges. Listed starting prices range from $0 for Firebase and PlayFab to $85 for Xano; those figures do not establish your production bill. Ask vendors for estimates using your workload.
