Clerk

Authentication built for modern React and Next.js apps

Developer Tools85/100

Developer-first authentication platform with pre-built React components (SignIn, UserButton, UserProfile) and deep Next.js App Router integration. Free tier includes 10,000 MAUs. Paid starts at $25/month + $0.02/MAU above 10K. Typically 40-60% cheaper than Auth0 for apps under 50K MAUs without enterprise SSO requirements.

Our take

Clerk is the auth choice for modern Next.js and React developers — the pre-built components (SignIn, UserButton, UserProfile, OrganizationProfile) eliminate days of auth UI work. Deep App Router integration means server-side auth is a one-liner. The 10K free MAU tier is the most generous in the category. Main limitation: SAML SSO and enterprise compliance features require Enterprise (custom pricing), which means Auth0 remains necessary for B2B SaaS targeting enterprise buyers from day one.

Product roadmap

Clerk is expanding B2B auth features (custom domains per organization, per-org branding) and deeper Next.js middleware integration. Passkey support and AI-powered anomaly detection are active development areas.

Who is Clerk for?

Solo(1 person)
Great fit

Best auth option for Next.js indie developers. Pre-built components, 10K free MAUs, and TypeScript support. Production auth in an afternoon.

Small team(2–20 people)
Great fit

The default auth choice for Next.js/React startups. Pro at $25/month covers early growth. Upgrade to Enterprise when your first enterprise customer asks for SAML.

Mid-size(21–200 people)
Good fit

Scales cleanly for consumer apps. B2B SaaS teams selling to enterprise may hit the SAML SSO requirement earlier than expected.

Large org(201–1,000+)
Mixed fit

Large teams with enterprise identity requirements typically migrate to Auth0 or build on Okta. Clerk's Enterprise tier is maturing but less proven at this scale.
