About

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.

About

Cerbos is an authorization management platform for defining, deploying and evaluating access-control policies across applications and services. Developers can use its policy decision point (PDP) to evaluate authorization requests, while teams author and manage policies for role-, relationship- and attribute-based access control. Cerbos supports local, self-hosted and cloud-based workflows, with policy testing, observability and audit information for reviewing authorization decisions. Cerbos Hub provides a managed environment for organizing and distributing policies, and the open-source Cerbos PDP can be deployed alongside application workloads. The platform is intended for engineering, security and product teams that need consistent, fine-grained authorization for users, services and other identities across distributed systems.
