Best For
Enterprise on-prem identity; legacy system integration; organizations standardized on Red Hat / Java stacks
AI apps built on the Supabase BaaS stack; projects that need auth + database + storage in one platform
Limitations
No agent SDK, no FGA, no human-in-the-loop; UI and developer experience are dated; heavy Java-based deployment
Auth is tightly coupled to Supabase's ecosystem; no token delegation, no FGA, no agent SDK; auth is secondary to the BaaS offering
