Organizations requiring a tool to build fast and secure authorization systems

About AuthZed

Unblock your business with an authorization system inspired by Google's Zanzibar white paper. As the creators of SpiceDB, the AuthZed team delivers enterprise-ready permissions systems built for scale and security. The most mature open source Zanzibar implementation designed for both consistency and performance at scale. Define fine-grained access for any object in your application or across your product suite and manage permissions using a centralized schema. Specify consistency requirements per authorization check; tunable consistency features balance performance and correctness according to your use case. SpiceDB returns lists of authorized subjects and accessible resources, helpful when pre-filtering permission-based results. Instrumented with observability tooling, a powerful Kubernetes operator, and load-testing capabilities, SpiceDB prioritizes both developer and platform engineering experiences.
