Free platform Auth allowance · USD 0 within Free platform allowances · Monthly allowance. 50,000 regular monthly active users; Free permits two active projects and can pause inactive projects after one week. Official source ↗
Limits to check
Authorization policies remain the developer’s responsibility; platform resources, SSO, advanced MFA and email/SMS delivery can introduce separate costs.

Research scope & testing evidence
Our evaluation
Supabase Auth is especially coherent when the application already uses Supabase Postgres and needs identity to connect closely with data access. Authentication supplies a user and session; Row Level Security can then enforce which records that user may read or change. Those policies still have to be designed and tested. A successful login does not prove that two customers are isolated. The free monthly-active-user allowance is useful for a pilot, but production costs also depend on the platform plan, compute and delivery providers. SSO and advanced authentication features have separate meters or add-ons. Evaluate recovery, logout and expired sessions alongside the happy path. A team adopting only authentication should consider whether the platform dependency and its operating model suit the rest of its architecture.
