Short description Permit.io provides authorization-as-a-service with a low-code policy management interface, RBAC/ABAC/ReBAC policy support, and a managed policy decision layer — enabling teams to ship fine-grained access control without building it from scratch. OpenFGA is an Apache 2.0 authorization engine, inspired by Google's Zanzibar paper, that stores relationship tuples and answers permission checks via gRPC/HTTP APIs. Originally built by Auth0/Okta, it is now a CNCF Incubating project with a hosted Auth0 FGA option.
