Open Source, Google Zanzibar-inspired permissions database to enable fine-grained access control for customer applications


What is SpiceDB?

SpiceDB is a graph database purpose-built for storing and evaluating access control data.

As of 2021, broken access control became the #1 threat to the web¹. With SpiceDB, developers finally have the solution to stopping this threat the same way as the hyperscalers.

Why SpiceDB?

- World-class engineering²: painstakingly built by experts that pioneered the cloud-native ecosystem
- Authentic design³: mature and feature-complete implementation of Google's Zanzibar paper
- Proven in production⁴: 5ms p95 when scaled to millions of queries/s, billions of relationships
- Global consistency⁵: consistency configured per-request unlocks correctness while maintaining performance
- Multi-paradigm⁶: caveated relationships combine the best concepts in authorization: ABAC & ReBAC
- Safety in tooling⁷: designs schemas with real-time validation or validate in your CI/CD workflow
- Reverse Indexes⁸: queries for "What can subject do?", "Who can access resource?"
