Is Clerk worth the price?

Good value

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.

Hidden Costs & Gotchas

SMS authentication costs $0.01 per message (US/CA), adds up for MFA-heavy apps

MRU counts retained users, not active, deleted users still count until month resets
