- Casbin is a powerful and efficient open-source access control
library that supports multiple authorization models
- Open Poicy Agent (OPA) is a policy engine that streamlines policy
management across your stack for improved development, security
and audit capability.
- OpenFGA is an open-source authorization solution that allows
developers to build granular access control using an easy-to-read
modeling language and friendly APIs.
- I think OpenFGA (and SpiceDB) are implementations of Google's
Zanzibar paper.
