Best For
Next.js and React AI apps needing fast auth setup with prebuilt UI components
AI apps built on the Supabase BaaS stack; projects that need auth + database + storage in one platform
Limitations
JavaScript/TypeScript only; no token delegation or FGA; not designed for complex agent authorization patterns
Auth is tightly coupled to Supabase's ecosystem; no token delegation, no FGA, no agent SDK; auth is secondary to the BaaS offering
Supported Not supported Unverified
