Supabase

Postgres BaaS with auth and storage

Free tier + paidDatabases & backendsupabase.com

What it is

Managed Postgres plus auth, row-level security, file storage, realtime subscriptions and edge functions, all open source and self-hostable. Free tier gives 500MB database, 1GB storage and 50,000 monthly active users across 2 active projects. Pro is $25/mo with $10 of compute credit included.

Why it earns a slot

The default backend for AI builders — Lovable Cloud runs on Supabase behind the scenes, and Bolt and v0 wire it up natively. Its official hosted MCP server lets agents run migrations, inspect schemas and manage branches directly.

Know before you commit

Free projects pause after 1 week of inactivity and you get only 2 active ones. Egress and compute overages on Pro add up faster than the $25 headline suggests.
