The Best Supabase Alternatives in 2026 (and When You Don't Need to Switch)

Serverless Postgres with git-style database branching and scale-to-zero. It is the database half of Supabase, minus auth, storage, and the lock-in.

Use when

You already run your own auth (Clerk, Auth0, NextAuth), you want a branch of your database per pull request, or you are cost-sensitive and want to stop paying when idle. Standard Postgres wire protocol means almost zero migration risk.

Skip when

You actually want the all-in-one bundle. Neon is only the database. You will be wiring up auth, storage, and realtime yourself, which is exactly the work Supabase does for you.

A reactive, TypeScript-native backend where your queries are functions and the UI updates itself. A genuinely different model, not a Supabase clone.

Use when

You are building a highly interactive realtime app (collaboration, live dashboards, chat) and your team loves TypeScript. Realtime is on by default with consistency guarantees Supabase Realtime does not give you out of the box.

Skip when

You need real Postgres and SQL. Convex uses a custom document store, so you are trading SQL familiarity and portability for developer experience. That is moderate lock-in, even though the backend is now open-source.

Open-source, self-hostable BaaS with the full Supabase feature set: database, auth, storage, functions, plus both REST and GraphQL.

Use when

Vendor lock-in is a real concern for your org and you want to own the whole backend on your own infrastructure. The self-hosted version is a complete platform with no per-seat tax.

Skip when

You are Postgres-committed. Appwrite is MariaDB-based, so it is not a drop-in for SQL-heavy Supabase apps. Self-hosting also means you now own the uptime, backups, and patching.

A single Go binary that gives you a database, auth, file storage, realtime, and an admin UI. Dead-simple to deploy, free forever.

Use when

You are building internal tools, prototypes, or a small-to-medium app and want zero platform overhead. One binary, SQLite, no Kubernetes, no monthly SaaS bill. Hard to beat for the long tail of small projects.

Skip when

You expect heavy concurrent writes or large scale. SQLite has a single-writer model, and the community is smaller than Supabase's. Wrong tool for a high-throughput production system.

Google's original BaaS. Unmatched mobile SDKs, offline sync, and realtime, built around a NoSQL document database instead of Postgres.

Use when

You are building mobile-first, you need rock-solid offline sync, and your data is document-shaped rather than relational. Firebase's mobile SDKs are still the best in the business.

Skip when

You want relational data, SQL, or to avoid Google lock-in. Firestore is NoSQL, the pricing surprises are legendary, and migrating off the Google ecosystem is painful. The opposite of Supabase's Postgres pitch.
