About:
Permify is an open-source authorization service that implements the Google Zanzibar model for consistent, low-latency permission checks. It allows developers to define complex authorization schemas and relationships as code, centralizing access control logic. Its main value is providing a scalable, real-time authorization layer for applications and microservices.
Key Features:
  • Google Zanzibar-inspired architecture
  • Relationship-Based Access Control (ReBAC)
  • Real-time permission evaluation
  • Policy as code with a custom DSL
  • Golang-based high-performance engine
Use Cases:
  • Implementing fine-grained user permissions in SaaS applications
  • Centralizing authorization logic across a microservices architecture
Alternatives:
  • OPA (Open Policy Agent) – OPA is a general-purpose policy engine using Rego, while Permify is specialized for authorization with a Zanzibar-inspired data model.
  • SpiceDB – Both are Zanzibar implementations; SpiceDB is the reference implementation by AuthZed, Permify is an alternative service with its own tooling.
