Auth is deceptively complex. Get it right the first time.
Auth0, Clerk, Firebase Auth, Supabase Auth, NextAuth.js — each makes different tradeoffs between flexibility, cost, and developer experience.
Why this decision matters
Auth touches every part of your application — routes, API calls, database queries, user experience. Switching auth providers means rewriting middleware, migrating user data, and updating every protected endpoint. It's one of the most painful migrations in software.
What we evaluate
We consider your framework (React, Next.js, etc.), whether you need SSO/SAML for enterprise customers, social login requirements, pricing model, pre-built UI components, and the quality of SDK documentation.
Common mistakes
Building auth from scratch "to save money" — it always costs more in security incidents and development time. Choosing an enterprise solution for a side project. Ignoring webhook support when you need user sync across services.
