Permit.io

Permit.io is an authorization control plane designed to manage what AI agents and applications can do across all the systems they access. It provides centralized, fine-grained policy management so teams can define and enforce who (or which agent) is allowed to perform specific actions, on which resources, and under what conditions. The platform focuses on runtime enforcement, ensuring that access decisions are applied at the moment actions are requested, not just at configuration time.

Key capabilities include policy-based access control (PBAC) with support for role-based, attribute-based, and relationship-based models, allowing precise control over complex authorization scenarios. Permit.io integrates with existing identity providers, services, and data stores, enabling consistent authorization rules across microservices, APIs, backends, and AI agent workflows. It offers a policy editor, audit logs, and policy simulation tools to help teams design, test, and troubleshoot access rules safely before deployment. The system also supports distributed enforcement via SDKs, sidecars, and APIs, so decisions can be enforced close to where actions are executed.
