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

Love SpiceDB but not the idea of running a highly available, globally distributed, and mission-critical service? The AuthZed team is here to take the pager!
