Clerk
Clerk · Developer & Infrastructure
Modern authentication platform positioned as the alternative to Auth0 for React and Next.js developers. Distinctive for pre-built UI components (SignIn/SignUp forms) that install in one line — you don't build auth UI from scratch. Free tier bumped to 50K MAU in Feb 2026 (industry-leading). Pro $25/mo includes 1 SSO connection (WorkOS charges $125/mo for the same). Business $300/mo. Popular with Series A/B React startups.
In other words, Clerk is the auth-as-a-service for developers building Next.js / React apps who want user management + social login + billing + orgs shipped in an afternoon — not weeks. Free tier covers up to 10K MAUs; Pro adds SSO, advanced features, and higher limits. Extremely easy for React/Next.js developers; more setup work outside that stack. Deep native integrations with Next.js, Vercel, Supabase, and modern JS ecosystem. Downside: pricing scales aggressively past 10K MAUs, and non-JS backends (Ruby, PHP) have thinner SDK support.

Depends on tier
CONFIRMED UNCHANGED 2026-09-15. Pro $25/mo monthly / $20 annual and Business $300/mo both re-confirmed; Free (Hobby) still 50,000 MRU (clerk.com/articles, checkthat, costbench, idsync, budgetforge agree). Pro overage confirmed at $0.02 per additional MRU with volume discounts down to $0.012 at 10M+. No vendor pricing-change announcement located. No movement, no snapshots written. BILLING-UNIT NOTE (not a price movement): Clerk meters monthly RETAINED users (MRU), not MAU — a user only counts once they return at least 24 hours after signup. This makes Clerk's headline cheaper than per-MAU competitors at equal nominal user counts; worth surfacing on the frontend when comparing against Auth0/WorkOS/Supabase.
No separate trial
Non-JS stack or open-source preference? Pick Auth0, Supabase Auth (bundled), or Kinde. Ultra-simple email/password only? Firebase Auth (free).
