Pick this one for full control over the database and auth layer; pick the Supabase version to skip building auth yourself.",{"question":906,"answer":907},"Should I use Auth0 or Supabase Auth for authentication?","Auth0 is the better default if you want a mature, general-purpose identity platform with social logins and MFA built in, verified from FastAPI route dependencies via its official Python SDK. Supabase Auth is the lighter option if you just need email\u002Fpassword and OAuth logins backed by a hosted user table, without adopting the rest of Supabase's platform.",{"question":909,"answer":910},"Can I switch from self-hosted PostgreSQL to Neon or Prisma Postgres later without a rewrite?","Yes. This stack has no fixed ORM, so switching database vendors is a connection-string change in whichever client library you use (SQLAlchemy, asyncpg, or similar), not a schema or query rewrite, as long as you're not relying on a Postgres extension the serverless option doesn't support.",{"question":912,"answer":913},"What's the cheapest way to run this stack?","Self-hosted PostgreSQL and skipping the paid addition tools cost nothing beyond hosting.
