Fine-Grained Authorization
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.
Casbin is a powerful and efficient open-source access control library that supports various access control models for enforcing authorization across the board.
Enforcing a set of rules is as simple as listing subjects, objects, and the desired allowed action (or any other format as per your needs) in a policy file. This is synonymous across all flows in which Casbin is used. The developer/administrator has complete control over the layout, execution, and conditions for authorization, which are set via the model file. Casbin provides an Enforcer for validating an incoming request based on the policy and model files given to the Enforcer.
