What people are saying

Trusted by startups and the world's largest companies

  • Clerk let us ship secure, multi-tenant auth in our Next.js app fast—route protection, organization switching, and server-side auth() checks just work. Webhooks keep our user and organization data in sync, so we can focus on building Outlit instead of auth plumbing.

  • Quality and consistency in design is everything to us - Clerk allowed us to go live immediately, while also allowing us to follow on with tailor made auth components using the same SDK. Release now, customize later.

  • Clerk took the pain out of auth for us. Multi-tenant workflows and SSO were surprisingly easy to implement, customization was flexible enough to match our product, and onboarding just worked. It removed complexity we would have otherwise had to build ourselves.
