Is Clerk worth the price?
8/10
Clerk offers the most developer-friendly auth with 50K free users — enough for most startups to reach revenue before paying.
Pro at $20/mo is reasonable, but SMS and enterprise SSO add-ons can surprise you.

How Clerk Compares to Competitors
Auth0 free tier caps at 25K MAU (vs Clerk 50K) and charges $240/mo for B2B features. Supabase Auth is free with self-hosted but lacks pre-built UI. Firebase Auth is free to 50K MAU but has no embeddable components. Clerk wins on DX and React integration.
