{"id":82541,"title":"Stack Auth — Open-source user authentication that doesn't suck","tagline":"The open-source alternative to Auth0, Clerk, and Firebase Auth. Fully managed \u0026 supports authorization.","body":"**Docs**: [https://docs.stack-auth.com](https://docs.stack-auth.com/)\\\n**Star us on GitHub**: \u003chttps://github.com/stack-auth/stack\u003e \n\n![uploaded image](/media/?type=post\u0026id=82541\u0026key=user_uploads/1147249/8ef50525-682e-424a-8fab-58e64897602c)\n\nHi all! We're [Zai](https://www.linkedin.com/in/zaishi) and [Konsti](https://www.linkedin.com/in/stan-wohlwend-b30340167/), and we’re repeat founders who believe that devtools must be dev-friendly.\n\nUser authentication _sucks_. Existing solutions are a pain to set up and have hostile pricing, terrible documentation, and vendor lock-in. The few good solutions that exist only do authentication and don't even touch **authorization** or **user management**.\n\nStack Auth was born out of years of frustration. We wanted to build something better.\n\nIf you're building B2B software, we'll deal with **organizations**, **permissions**, and **RBAC** for you.\n\nIf you're building a Next.js app, we have **React components** for sign-in, password reset flows, and all sorts of things like account settings and teams. And they're customizable.\n\nOther features include:\n\n* **100% open-source** and self-hostable, though we also provide a Cloud service\n* **User dashboard** to view, modify, and understand your users\n* **Multi-tenancy** for your business customers\n* **Access token management** for APIs of OAuth services that users connect with\n* **Impersonation** to log in as one of your own customers for debugging and live support\n* **Webhooks** to sync your data with other systems like databases or Slack\n* **Customizable e-mails** on triggers such as user sign-up\n* **Flexible REST API** for use with any backend\n\nInterested? Check out [our website](https://stack-auth.com/) or [schedule a call](http://cal.com/team/stack/chat). Or take a look at the screenshots below.\n\nThanks all!\n\n![uploaded image](/media/?type=post\u0026id=82541\u0026key=user_uploads/1147249/7d1ffe2b-bec6-487c-8c91-edf4e13cee71)\n\n![uploaded image](/media/?type=post\u0026id=82541\u0026key=user_uploads/1147249/514ca5a4-fe6a-4482-b88e-a75cf6127627)\n\n![uploaded image](/media/?type=post\u0026id=82541\u0026key=user_uploads/1147249/f8d922e0-3594-442f-bc96-ed852a2e2205)\n\n","slug":"LTJ-stack-auth-open-source-user-authentication-that-doesn-t-suck","created_at":"2024-07-29T22:15:05.983Z","updated_at":"2026-05-02T07:41:41.524Z","total_vote_count":58,"url":"https://www.ycombinator.com/launches/LTJ-stack-auth-open-source-user-authentication-that-doesn-t-suck","share_image_url":"https://www.ycombinator.com/media/?type=post\u0026id=82541\u0026key=user_uploads/1147249/7d1ffe2b-bec6-487c-8c91-edf4e13cee71","company":{"id":29642,"name":"Stack Auth","slug":"stack-auth","url":"https://stack-auth.com","logo":"https://bookface-images.s3.amazonaws.com/small_logos/7c58aadee870eec1472167cb5194bd295f5285f8.png","batch":"Summer 2024","industry":"B2B","tags":[],"search_path":"https://bookface.ycombinator.com/company/29642"}}
