Clerk

to build AgentQL

We initially began building user management in-house but quickly realized that creating a secure and seamless user experience involved more complexity than anticipated. It was clear that continuing down this path would pull valuable engineering resources away from our core product. Clerk provided a comprehensive solution, covering everything from account life cycle to payment integration. This shift allowed us to focus on our primary goals while still ensuring a great user experience.

to build Pull Sense

•15 reviews

Clerk makes authentication effortless, with a developer-friendly API and prebuilt UI components that save time. Unlike Auth0 or Firebase Auth, Clerk provides first-class support for modern frameworks like Next.js and integrates seamlessly with Supabase and Vercel. The built-in user management, multi-factor auth, and social logins simplify everything, while its flexible session management ensures security without complexity. For PullSense, it made user authentication seamless without the usual headaches.

Clean APIs, great UI components, and sensible defaults meant we didn’t have to reinvent authentication. It handled the hard parts so we could focus on the product.
