What Is Supabase? Database Software Overview & Pricing

Overview

Supabase describes itself as the Postgres development platform: every project is a dedicated PostgreSQL database, optionally combined with authentication (20+ social sign-in providers, email, phone and magic links, with authorisation via row-level security), S3-compatible storage with a CDN, TypeScript edge functions, realtime WebSocket sync, auto-generated APIs and pgvector-based vector search^[22]. Its core is open source^[22].

The Free plan includes a 500 MB database per project, a shared CPU with 500 MB of RAM, up to 50,000 monthly active users, 5 GB of egress and 1 GB of file storage, but limits accounts to two active projects, pauses projects after a week of inactivity and excludes automatic backups^[21]. Pro starts at US$25 per month and Team at US$599 per month, each including 8 GB of disk per project and then US$0.125 per GB; Enterprise is custom^[21]. Supabase gives small teams a full backend quickly while keeping standard PostgreSQL underneath, which eases later migration. Usage-based compute and egress charges need monitoring as applications grow, and the free tier is unsuited to production.
