  "tier": "mixed",
  "pick": false,
  "what": "Authentication built into the Supabase Postgres platform. Users live in an <code>auth.users</code> table inside your own database, and row-level security policies read the JWT directly. The free tier covers 50,000 monthly active users; the $25/mo Pro plan includes 100,000 then charges $0.00325 per extra MAU.",
  "why": "If your data already sits in Supabase, auth is effectively free and authorization becomes a SQL policy instead of application middleware you have to remember to apply.",
  "warn": "Per-MAU overage is the cheapest in this list, but SAML SSO is billed separately at $0.015/MAU. Free projects pause after a week of inactivity, and misconfigured row-level security is a common route to leaking a whole table publicly.",
