## Summary

Permit.io provides authorization as a service with a policy editor, audit logs, and SDKs that decouple permissions from application code for any stack.

## Company Overview

Permit.io is an authorization platform founded in 2021 that provides developers with a complete solution for implementing fine-grained access control in their applications. The platform offers a cloud-hosted policy decision point, a visual policy editor for defining roles and permissions, real-time audit logging, and multi-framework SDK libraries for Python, Node.js, Java, and other languages. Permit.io is built on top of open-source policy engines including OPA (Open Policy Agent) and Casbin, providing an enterprise-ready hosted service layer on top of proven open-source foundations. The company raised $7M and targets engineering teams that need to implement permission models ranging from simple RBAC to complex ABAC and relationship-based access control without building policy infrastructure from scratch. Permit.io's developer-first approach includes GitOps integration for managing policies as code and a sandbox environment for testing permission changes before production deployment. The platform serves SaaS companies, enterprise applications, and multi-tenant platforms that require auditable, testable access control that can evolve as product requirements change.

## Frequently Asked Questions

### What is Permit.io?
Permit.io is an authorization-as-a-service platform with a visual policy editor, audit logs, and SDKs that allows developers to implement fine-grained RBAC, ABAC, and relationship-based access control without building policy infrastructure.

### What open-source foundations does Permit.io use?
Permit.io is built on open-source policy engines including OPA (Open Policy Agent) and Casbin, providing a managed service layer with visual tooling and enterprise features on top of battle-tested open-source authorization foundations.

### How does Permit.io handle policy changes?
Permit.io supports GitOps-style policy management where permissions are defined as code that can be versioned and reviewed, with a sandbox environment for testing permission changes before deploying them to production.

### What authorization models does Permit.io support?
Permit.io supports Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), and Relationship-Based Access Control (ReBAC) — covering everything from simple admin/user roles to complex permissions where access depends on data attributes or relationship graphs between users and resources.

### How does Permit.io integrate with application code?
Permit.io provides SDKs for Python, Node.js, Java, .NET, Ruby, and Go that make a simple permission check call — typically permit.check(user, action, resource) — which evaluates against the policy defined in the Permit.io dashboard and returns allow or deny without application code containing any permission logic.

### Can Permit.io work with existing identity providers?
Yes. Permit.io integrates with existing identity providers including Auth0, Okta, Cognito, and any OIDC-compatible service, using user identity data from those providers to evaluate permissions without replacing your authentication layer.

### Does Permit.io support audit logging?
Yes. Permit.io records a complete audit log of every permission decision, including which user, resource, and action were evaluated, what the outcome was, and which policy rule applied — supporting compliance requirements for SOC 2, HIPAA, and other frameworks that require access control audit trails.

### What is the performance impact of using Permit.io for permission checks?
Permit.io runs a local policy decision point (PDP) as a sidecar container or agent alongside your application, so permission checks are evaluated locally without network round trips to Permit.io's cloud — providing sub-millisecond decision latency even at high request volumes.
