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!

I've moved my webapp from Clerk to Stack Auth in hours. It's great to have an open-source alternative. The team has been very responsive and I'm happy to be an early adopter. Best of luck guys!

@fomalhaut This good product is very interesting, I hope it can help users and congratulations on the launch of your newest product

Gotta upvote another open source project that makes it easy to build auth related functions for developers who honestly don't have much resources to deploy in this area but auth is so crucial to so many industries. Congrats @fomalhaut and team on the team!

Great to see this, I had been very frustrated with the auth options recently, and it's exciting it's open source as well.

I love the idea of having managed authentication that is also customizable. This could really simplify a lot of development projects.

I am excited about the potential this has for streamlining authentication processes. The quick setup and useful components make it a valuable tool.

The developer-friendly nature of this is a huge plus. It's fantastic to see such a robust solution that's easy to integrate and use.

I appreciate that it's fully open-source and self-hostable. This gives a lot of flexibility and control over user authentication and authorization.

I am impressed with how quickly you can set this up. It’s great to see a tool that’s both powerful and user-friendly for developers.

Hai @fomalhaut what have you launched today, the product is very impressive, hopefully it can become a pillar or bridge that can make things easier and can be useful in the future, and congratulations on the launch 🎉🎊👏

I'm curious why you guys decided to go in more of the Auth0/Clerk direction than the Keycloak one? It seems that there are a bunch of open source alts to Auth0/Clerk, but not really Keycloak and Keycloak is where I have all the pain.

Congratulations on the launch!🎉 Looks super promising, going to give it a try soon.

Hi Stack Auth team! Congrats on the launch. How does Stack Auth’s open-source approach provide flexibility and control compared to proprietary solutions like Auth0 and Firebase Auth?
