Stack Auth (YC S24)

Open-source Auth0/Clerk alternative

Stack Auth is managed user authentication & authorization. It is developer-friendly and fully open-source & self-hostable. Within 5 minutes, you can setup Stack and use its components such as <SignIn /> and <AccountSettings />.

Hi Product Hunt, Zai & Konsti here! We built many web projects before, and the most annoying part of starting a project is spending countless hours battling with authentication, user management, account settings, and RBAC. None of the open-source solutions have the developer-friendliness and the feature set we'd wish for. We want to solve this problem for everyone with a great all-in-one open-source and self-hostable platform. We have paid managed hosting available on our platform, which will give you the same experience as Clerk or other services. However, we build trust with our customers and avoid vendor lock-in by keeping all infrastructure 100% open-source. If you like what we're building, please try it out in your project! Also, join our Discord to build great things together!
