SpiceDB
The open–source Zanzibar database — schema language, modeling, operations, and the gRPC / HTTP APIs.
Everything you need to build with SpiceDB.
Relationship-based access control, the Google Zanzibar way: model a schema, write relationships, and call CheckPermission from your code. Quickstarts, schema modeling, client SDKs, and full gRPC and HTTP API references — for the open-source SpiceDB engine and the managed AuthZed platform.
