SpiceDB: inspired by Google's ZanzibarEvolved 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
