- AI features that need vector search next to regular application data
Not a good fit for
- Always-on free projects: free projects pause after 1 week of inactivity
- Teams that don't want to write SQL or Postgres policies for access control
- Predictable flat bills at scale: database size, users, storage and egress above the plan limits are billed per unit

- Authentication
- Built-in user sign-up and sign-in. The free plan covers 50,000 monthly active users and Pro covers 100,000.
- Row level security
- Access rules are written as Postgres policies, so the same rules apply to every client and API.

- Edge Functions
- Server-side functions for custom logic, alongside Postgres database functions.
- Vector toolkit

About Supabase
Supabase gives every project a full Postgres database and builds backend services around it. Tables get REST and GraphQL APIs automatically, row level security policies in Postgres control who can read and write each row, and clients can subscribe to changes over Realtime.
Around the database it adds user authentication, file storage, database functions and Edge Functions, plus a vector and embeddings toolkit for AI features. Everything is managed from a web dashboard, and the whole stack is open source under Apache-2.0, so it can also be self-hosted.
Supabase was founded in 2020 and is based in San Francisco. In June 2026 it raised a $500 million Series F at a $10.5 billion valuation and said it had more than 9 million developers and over 250,000 customers.
