Stack Auth (YC S24)

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!Konsti here, thanks for all the comments!

Lots of people are asking about our competitors, so here's how we're different. Think of a specific competitor and ask yourself:

• Are they open-source?
• Are they developer-friendly, even for startups and indie devs, letting you get started & scale in minutes?
• Besides authentication, do they also do authorization and user management, with features that you'll inevitably need (such as; multi-tenancy with teams/organizations, role-based access control, password authentication, user dashboard, analytics integration)?

How many YESes did you get? The answer is YES for Stack Auth on all three.@kjosephabraham Thanks! We've both built startups before, and we found that one of the most painful aspects in the early stages was building things that weren't directly related to our core business. We spent a lot of time on tasks like authentication, user management, database migration, analytics, and billing. Our long-term vision is to solve all these problems with a five-minute setup and manage everything within one dashboard. We decided to tackle this from the most core and painful problem, which authentication!@fomalhaut Wow, this looks super promising, will use it in my next project. Congratulations on the launch!I've used Auth0 and Supabase Auth. I just tried Stack Auth, and it’s very simple and intuitive. I've decided to use it in my next project.

What's even more impressive is that it's open source!

Congrats on the launch, great job!!!!!!@bonvisions Glad you like it! Thanks so much!Congratulations on the launch. This looks clean. Curious to know how different it is from next-auth. also can we customize the sign in pages without using the stack components?@madospace Hi Madhu, thank you for your support!

Differences from Next-Auth: We just have more features — for example, we have built-in support for teams/organizations, RBAC, password auth, JWT metadata, and so on and so forth. We are a managed solution for authentication, authorization, and user management, whereas Next-Auth is simply a library for authentication only.

About customization: Yes, everything is fully customizable! You can build your own button and call a function like stackApp.signInWithOAuth("google") when clicking it.Seems to have a good dashboard - this feature is key in my opinion to have the overview of implementations

Congrats on the launch 🚀
