Permit.io
Fine-grained authorization and access control for apps, APIs, and AI agents
About Permit.io
Permit.io is a full-stack authorization platform that lets engineering teams add and manage fine-grained access control in their applications without building permission logic from scratch. It supports every major authorization model out of the box, including role-based access control (RBAC), attribute-based access control (ABAC), and relationship-based access control (ReBAC), all configurable through a no-code UI, API, or policy-as-code with GitOps workflows. Under the hood, Permit decouples policy from code by deploying Policy Decision Points (PDPs) as microservices that return authorization decisions in sub-millisecond time, so checks stay fast even at scale. Beyond traditional app permissions, Permit has positioned itself for the AI era with tooling for agentic authorization, including an MCP gateway that gates token and tool access for AI agents in real time, human-to-agent delegation, and consent frameworks. With SOC 2 Type II certification and HIPAA, GDPR, and CCPA support on higher plans, Permit targets engineering and security teams in fintech, healthcare, and other regulated industries that need consistent, auditable access control across distributed systems.
