Permify
Permify is an authorization service designed to help developers build and manage fine-grained, scalable access control systems within their applications. Inspired by Google's Zanzibar, Permify enables the structuring of authorization models, storage of authorization data in preferred databases, and interaction with its API to handle authorization queries across various applications and services. It supports multiple access control models, including Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC), allowing for the creation of granular permissions and policies. Permify centralized authorization logic, abstracting it from the codebase to facilitate easier reasoning, testing, and debugging. It offers flexible policy storage options and provides a role manager to handle RBAC role hierarchies. The platform also supports filtered policy management for efficient enforcement in large, multi-tenant environments.

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.

Cedar
Cedar is an open source policy language and evaluation engine developed by AWS to facilitate fine-grained access control in applications. It enables developers to define clear and concise authorization policies, decoupling access control from application logic. Cedar supports common authorization models, including role-based access control and attribute-based access control, allowing for expressive and analyzable policy definitions. Its design emphasizes readability and performance, ensuring that policies are both easy to understand and efficient to enforce. By integrating Cedar, applications can make precise authorization decisions, enhancing security and maintainability. The policy structure is designed to be indexed for quick retrieval and to support fast and scalable real-time evaluation, with bounded latency. It enables analyzer tools capable of optimizing your policies and proving that your security model is what you believe it is.
