Discover top open-source software, updated regularly with real-world adoption signals.

Fast, developer-friendly authentication with built-in dashboard and RBAC
Stack Auth delivers instant sign-in, sign-up, and user management for Next.js and React apps, offering OAuth, passkeys, multi-tenancy, RBAC, and a ready-made dashboard—all deployable in minutes.

Stack Auth is a managed authentication platform designed for modern JavaScript teams. It works out-of-the-box with Next.js, React, and any backend that can call its REST API, letting developers focus on product features instead of security plumbing.
The solution includes ready-made and components, a user dashboard, account settings, multi-tenancy, role-based access control, OAuth connections, passkey support, impersonation, webhooks, and automatic email templates. After a five-minute wizard you receive API keys, drop them into a .env file, and your app is ready to authenticate users. The managed service is optional; you can export data and self-host the dashboard for free. Development requires Node v20, pnpm, and Docker for the local stack, but production can run on any environment that supports the REST endpoints.
When teams consider Stack Auth, these hosted platforms usually appear on the same shortlist.
