Servicefreemium

Ory Keto is an open-source permission server based on Google's Zanzibar model. It answers fine-grained access questions for applications - who can see or act on which resource - over an API, and is designed for low latency across very large numbers of relationships. Teams can self-host it or use the equivalent managed service on the Ory Network.
