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.

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.

We needed production-ready authentication without slowing the team down. Clerk let us ship securely from day one and stay focused on core product work. Setup was fast, UX is polished out of the box, and it scales cleanly without us constantly revisiting edge cases.

Stop googling for a solution and just use this. This is likely exactly what you need. Clerk helps you avoid the hassle of having to deal with authentication both on the BE and the FE. It is not worth opting for another free/open-source solution as the free tier on Clerk is quite generous and will help you get started.
