Which tool for replacing Supabase?

People leave Supabase for a few recurring reasons. Free projects pause after a week of inactivity and you can only have 2 active ones, with 500 MB of database space. Pro starts at $25 a month and includes $10 of compute credit, enough for one Micro instance (1 GB RAM, shared CPU); every extra project adds at least $10, bigger instances run from $15 to thousands a month, egress costs $0.09 per GB above 250 GB, users $0.00325 each above 100,000, and SOC 2 reports and dashboard SSO need Team at $599. Others want a NoSQL database with offline mobile sync, or only a database without the rest of the platform. Before you switch, note that Supabase is already open source and plain Postgres, so its lock-in is low: staying on Postgres (Neon) keeps the move to a dump and restore, while auth users and stored files need their own migration, and moving to a document database (Firebase, Appwrite) means remodeling your data. We ranked the alternatives on data model, free plan limits and pausing, pricing at scale, lock-in, self-hosting and how much of the backend (auth, storage, functions, realtime) comes included. Prices checked November 13, 2026, US, on each vendor's pricing page.

Analyst verdictNeon8.5

The best Supabase alternative for most teams is Neon: it is also Postgres, so your schema, SQL and pg_dump backups move over unchanged, and its free plan covers 100 projects with 1 GB each and scales idle databases to zero instead of pausing them. Firebase is the best for mobile apps that need offline sync and realtime, but it is a NoSQL document database tied to Google. Appwrite is the best open-source all-in-one backend, with auth, storage, functions and hosting you can also self-host.

Best Supabase alternatives in 2026

01
Best overall alternative

Neon

Serverless Postgres, so the move from Supabase is a dump and restore. Free covers 100 projects with 1 GB and 100 CU-hours each, auth for 60,000 users and no weekly pause; paid usage is $0.106 per CU-hour. Its auth, storage and realtime are younger than Supabase's.

8.5Freemium
02
Best for mobile and realtime apps

Firebase

Offline sync, realtime listeners, auth for 50,000 users, push and crash reports in one Google console. NoSQL documents instead of tables, billed per read and write above the free daily quotas, and no self-hosting.

8.4Freemium
03
Best open-source all-in-one

Appwrite

Auth, databases, storage, functions, messaging and hosting in one project, self-hosted for free or in the cloud with 75,000 users free and Pro at $25 a month. You use its APIs instead of SQL.

FAQ

Questions buyers ask

What is the best alternative to Supabase?

Neon if you want to keep Postgres: your schema and SQL move over unchanged, the free plan covers 100 projects and idle databases scale to zero instead of pausing. Firebase for mobile apps that need offline sync and realtime. Appwrite for an open-source all-in-one backend you can self-host.

Supabase vs Firebase: which should I use?

Supabase if your data is relational: it is Postgres with SQL, joins and row-level security, open source and self-hostable, with Pro at $25 a month plus compute. Firebase if you build mobile apps that need offline sync, push notifications and realtime listeners out of the box, and you accept NoSQL documents, per-read billing and Google lock-in. Firebase now also offers Postgres through Data Connect on Cloud SQL, from $9.37 a month after a 3-month trial.

Is there a free Supabase alternative?

PocketBase is free and open source: one file that gives you a SQLite database, auth, file storage, realtime and an admin dashboard on your own server, though it is still before version 1.0, so updates can break compatibility. Appwrite is free to self-host. Among hosted free plans, Neon gives 100 projects with no weekly pause, and Firebase's Spark plan includes 1 GiB of Firestore and auth for 50,000 users.

Can I self-host a Supabase alternative?

Yes: Appwrite runs on your servers with Docker and covers auth, databases, storage, functions and hosting; PocketBase is a single binary for small apps. Supabase itself can also be self-hosted with Docker. Expect to own upgrades, backups and scaling. Firebase and Neon are managed services only.

What about Convex and PlanetScale?

Convex is a reactive backend for TypeScript apps: queries are TypeScript functions and results update live in the UI. Free includes 1 million function calls a month and Professional is $25 per developer a month, but it uses its own database and query model, not SQL. PlanetScale is a database only, with no auth or storage, and has no free plan: Postgres starts at $5 a month for a single node and $15 for a three-node high-availability cluster, and it also runs MySQL through Vitess.

Which Supabase alternative has the least vendor lock-in?

Anything that stays plain Postgres, such as Neon or a self-managed Postgres, because you can dump the database and restore it anywhere. Appwrite and PocketBase are open source, so you can always self-host, but your app code depends on their APIs. Firebase has the most lock-in: proprietary APIs, NoSQL data and no self-hosted version.
