What is Stack Auth?
Stack Auth provides a comprehensive open-source platform for authentication and user management, designed to simplify the implementation process for developers. The platform offers a wide range of features including organizations and teams management for B2B customers, permission trees with role-based access control (RBAC), and seamless integration with third-party OAuth APIs like Gmail and OneDrive without requiring complex OAuth flow management.
The platform includes beautifully styled components for quick setup, impersonation capabilities for debugging, both headless and headful UI options with shadcn/ui components, and a REST API for custom frontend and backend development. Stack Auth manages JSON Web Tokens (JWTs) and access tokens automatically, eliminating setup requirements while maintaining performance benefits. Additional features include webhooks for service synchronization and regular updates with new functionality.
