“I wanted something that wasn’t coupled to an identity provider, had proven scalability that could sustain any growth our product experienced, that was flexible, without the constraints of JWTs, and that could run across multiple regions to a global scale.”

SpiceDB: inspired by Google's Zanzibar
Evolved by AuthZed

The most mature open source Zanzibar implementation designed for both consistency and performance at scale.

Authorize anything, anywhere

Define fine-grained access for any object in your application or across your product suite and manage permissions using a centralized schema.

Minimize latency, maximize correctness

Specify consistency requirements per authorization check; tunable consistency features balance performance and correctness according to your use case.

Policy that scales

Determine attribute-based access (ABAC) with SpiceDB Caveats - our novel design for blending policy with a Zanzibar-based system.

Who has access?

SpiceDB returns lists of authorized subjects and accessible resources, helpful when pre-filtering permission-based results.

Ops-friendly permissions systems

Instrumented with observability tooling, a powerful Kubernetes Operator, and load testing capabilities, SpiceDB prioritizes both developer and platform engineering experiences.

Enterprise-ready products available
