Clerk alternative picks
Auth0
Enterprise-grade identity platform
Auth0 is the go-to for enterprise applications with complex auth needs. More powerful but more complex than alternatives.
Supabase Auth
Open source auth with PostgreSQL
Supabase Auth is the best value if you're already using Supabase. The free tier is unbeatable and RLS integration is powerful.
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.
