Overview
Supabase is a backend platform built around a dedicated Postgres database per project. On top of the database it adds authentication with 20+ social providers, S3-compatible file storage with a CDN, TypeScript edge functions on Deno, realtime change feeds over WebSockets and pgvector for embeddings. REST and GraphQL APIs are generated from your schema, and access is controlled with Postgres row-level security.
The free plan allows two active projects with a 500 MB database and 50,000 monthly active auth users, which covers many side projects. Free projects pause after a week with no activity and get no automatic backups, so it is not meant for production.
Paid billing has two layers. The Pro plan is $25 a month per organization and raises quotas (8 GB disk, 250 GB egress, 100,000 MAU, daily backups kept 7 days). Each project also runs on its own compute instance billed by the hour; a $10 monthly credit covers one Micro instance, and every additional project or larger instance is extra. Team at $599 a month adds SOC 2 and ISO 27001 reports, dashboard SSO and longer backup and log retention.
Because the stack is open source and the database is ordinary Postgres, you can self-host or move your data out with standard tools. Database branching, point-in-time recovery and log drains are metered add-ons rather than plan features.

What it does
- Dedicated Postgres
- Each project is a full Postgres database with 40+ preinstalled extensions, a table editor and SQL editor.
- Auth
- Email, magic link, phone OTP, 20+ social providers, anonymous sign-ins and SAML SSO, with authorization through row-level security.
- Auto-generated APIs
- REST via PostgREST and GraphQL via pg_graphql are generated from the schema without code generation.
- Storage
- S3-compatible object storage with CDN delivery and image transformations; uploads up to 50 MB on Free and 500 GB on paid plans.
- Edge Functions
- TypeScript functions on Deno with npm compatibility; 500,000 invocations free, 2 million on Pro then $2 per million.
- Realtime
- Database change listeners, presence and broadcast over WebSockets; 200 concurrent connections free, 500 on Pro.
- Branching
- Preview database branches per git branch, billed at $0.01344 per branch per hour on paid plans.
Strengths and limitations
Strengths
- Database, auth, storage, functions and realtime in one project with shared permissions
- Plain Postgres, so data and SQL skills stay portable
- Open source and self-hostable
- Free tier includes 50,000 auth MAU and two projects
- Regions across the Americas, Europe and Asia-Pacific, including several EU countries
Limitations
- Free projects pause after one week of inactivity and have no automatic backups
- Compute is billed per project, so several projects on Pro cost more than the $25 headline
- Point-in-time recovery costs $100/mo per 7 days of retention
- SOC 2 and ISO 27001 reports and dashboard SSO require the $599/mo Team plan
- No scale-to-zero: each paid project runs a compute instance around the clock
Who it suits
Good for
- Web and mobile apps that want auth, database and storage from one vendor
- Teams that prefer SQL and Postgres over a document database
- Prototypes that may grow into production without a migration
- Projects that need a self-hosting option later
Look elsewhere if
- Many small idle databases, where per-project compute adds up; a scale-to-zero Postgres fits better
- Teams that want only a database and no backend platform around it

Free plan loses email template editing on default SMTP

Questions
Is Supabase free?
Yes. The Free plan gives two active projects with a 500 MB database, 1 GB storage and 50,000 monthly active users, but projects pause after a week of inactivity.
How much does Supabase Pro cost?
Pro is $25 a month per organization and includes $10 of compute credit, enough for one Micro project. Each extra project adds at least $10 a month for its compute.
Can I self-host Supabase?
Yes. The core tools are open source and can be self-hosted.
Does Supabase have an EU region?
Yes. Projects can be placed in Frankfurt, Ireland, Paris or Stockholm, among 17 AWS regions.
Does Supabase include backups?
Pro includes daily backups kept for 7 days and Team 14 days. The Free plan has none, and point-in-time recovery is a paid add-on.
