What makers say

Makers on using it for authentication, from Product Hunt and Starter Story interviews, each linked to the source. Products with a page of their own and fuller notes first.

On Auth0

A huge thanks to Auth0 for helping us out with the authentication flow. They were really quick with the onboarding process and even with the support tickets.

SeyftAI, the makerSep 2026 ↗

For handling our user authentication with enterprise-grade security, so our users can log in instantly and focus on their data.

Ada.im, the makerSep 2026 ↗

I had a simple login system using Auth0 and it would unlock access to the premium content on the website.

On Clerk

The team loves Clerk for its intuitive interface, seamless integration, and efficient management of administrative tasks, allowing them to focus on building groundbreaking solutions.

Garple, the makerSep 2026 ↗

We used Clerk for account management. Building an authentication infrastructure from scratch is challenging, but by using Clerk’s abstracted API, we were able to simplify this process.

Hanabi.rest, the makerSep 2026 ↗

Nobody wants to worry about authentication or build their own system. Clerk allowed me to simply integrate them into my project and immediately feel confident in the security of my site.
