Supabase Auth alternative picks
Clerk
Drop-in authentication for modern apps
Clerk is the best choice for React/Next.js developers who want beautiful auth out of the box. The DX is unmatched, but costs can add up.
Auth0
Enterprise-grade identity platform
Auth0 is the go-to for enterprise applications with complex auth needs. More powerful but more complex than alternatives.
Firebase Auth
Google's authentication service
Firebase Auth is excellent for mobile apps and projects already in the Google ecosystem. Hard to beat on price.
Kinde
Modern auth built for growth
Kinde is a great up-and-comer with bundled feature flags. Worth considering if you need both auth and feature management.
