Last updated 3 months ago [Visit site](https://permit.io) Quick answer ## What is Permit.io? Short answer Permit.io is an authorization platform that provides a managed policy decision point alongside a low-code UI for non-engineering stakeholders to manage access control policies. It supports RBAC (role-based), ABAC (attribute-based), and ReBAC (relationship-based, like Google's Zanzibar model) access control, enabling complex permission structures without custom authorization code. Under the hood, Permit.io uses Open Policy Agent (OPA) and OPAL for policy evaluation and distribution. A key differentiator is the Permit.io Editor — a visual interface for defining and modifying policies without writing Rego directly. Verify current pricing at permit.io. Best for Engineering teams that need to ship fine-grained authorization across their application and want both programmatic API access and a low-code interface for policy administrators to manage permissions without engineering involvement. When to choose Choose Permit.io when you need a managed authorization service with both developer APIs and a low-code UI for non-engineering policy administrators, support for complex ReBAC models alongside RBAC/ABAC, and prefer a managed service over self-hosting. When not to choose Avoid Permit.io if you need fully self-hosted authorization with no external dependencies (use Cerbos or OPA directly), if evaluation volume pricing at your scale is prohibitive, or if you want the largest open source community (OPA is more established).
