supabase-auth
Teams already using Supabase for database and storage who want auth bundled into the same platform.
You gain platform cohesion and zero incremental cost but accept a less polished standalone auth experience.
Auth Providers
Managed authentication and identity platforms used for user login, session management, SSO, and access control in web and mobile applications.

Top pick for Solo Dev
clerk
Best combination of hosted UI, free tier, and fast time-to-working-login for a single developer.
Clerk combines polished hosted UI components, the strongest Next.js integration in the category, a generous free tier at 10K MAU, and high SDK quality without forcing teams into a broader platform commitment. It stays simple for solo builders, scales cleanly for startups, and avoids the integration complexity that comes with more enterprise-oriented providers.
