Permify

Permify is a open-source authorization service for creating and managing fine-grained permissions in your applications and services. Inspired by Google’s consistent, global authorization system, Google Zanzibar

Our goal is to make Google's Zanzibar available to everyone and help them build robust, flexible, and easily auditable authorization systems that perform well in scaled environments. With Permify, you can:

• Create permissions and policies using Permify's flexible authorization language that is compatible with traditional roles and permissions (RBAC), arbitrary relations between users and objects (ReBAC), and attributes (ABAC).
• Manage and store authorization data in your preferred database with high availability and consistency.
• Interact with the Permify API to perform access checks, filter your resources with specific permissions, perform bulk permission checks for various resources, and more.
• Test your authorization logic with Permify's schema testing. You can conduct scenario-based testing, policy coverage analysis, and IDL parser integration to achieve end-to-end validations for your desired authorization schema.
• Create custom and isolated authorization models for different applications using Permify Multi-Tenancy support, all managed within a single place, Permify instance.
