OpenFGA
Relationship-based access control made fast, scalable, and easy to use.

OpenFGA is an open-source authorization solution that enables developers to implement fine-grained, relationship-based access control. It draws on ideas from Google's Zanzibar paper and supports RBAC, ReBAC, and ABAC use cases through a human-readable modeling language and developer-friendly APIs. It is designed to answer authorization checks in milliseconds and scales from small projects to global enterprise platforms.
Developers define authorization models using OpenFGA's modeling language and query the API to check permissions, with the server running locally via Docker or in the cloud.
