What Permit.io does

Permit.io is an authorization platform for managing what users, services, and AI agents can do across the systems they touch. The product pages describe it as a control plane for agentic identity and fine-grained authorization, with enforcement centered on action-time checks rather than static access lists.

The site presents Permit as a fit for teams that need to define, enforce, and manage permissions through a combination of UI, API, SDK, and infrastructure-as-code workflows. It supports multiple authorization models, including RBAC, ABAC, ReBAC, and PBAC, so teams can start with a simpler model and move toward more contextual policies as application needs change.

Pricing is usage-based by monthly active users, with a free Community tier, a Startup tier, a Pro tier, and an Enterprise option with sales contact. The published pricing also emphasizes separate workspaces, environments, and deployment options for more advanced setups.

Core capabilities

Multiple authorization models

Permit supports RBAC, ABAC, ReBAC, and PBAC from the same product surface, so teams can choose a simpler model or move to more contextual authorization as needs grow.

Policy management across interfaces

The platform offers UI, API, SDK, and IaC paths for policy work, including no-code and low-code interfaces and policy-as-code generation into Git workflows.

Application enforcement

Permit documents API-driven authorization checks and embeds enforcement in application code with `permit.check(identity, resource, action)`. The RBAC and ReBAC pages both frame this as a direct integration path for apps.

GitOps and automated deployment

The pricing and model pages describe support for GitOps CI/CD, policy storage in Git, and automated deployment workflows for authorization changes.

Multi-project and multi-tenant modeling

The product pages describe shared workspaces, environments, projects, and multi-tenancy, with separate policy definitions per environment or silo.

Audit and decision logging

The pricing page includes operational audit logs, logs forwarding, and configurable retention, which supports review and monitoring of authorization decisions.

Practical use cases

Standard application RBAC
Build and manage role-based access in an application that needs straightforward permissions for users, tenants, and resources. The RBAC page shows role creation, assignment, and permission setup through a low-code UI and API.
Context-aware access policies
Add attribute-based rules when permissions depend on context such as user attributes, resource properties, or environment-specific conditions. The ABAC page positions the product as a way to move beyond static roles without giving up managed workflows.
Relationship-driven authorization
Model permissions around user-resource relationships, such as ownership, group membership, or parent-child structures. The ReBAC page describes graph-based relationship management and role derivation for this scenario.
AI agent permission control
Apply authorization to AI agents, tools, APIs, and data so agent actions are checked at runtime. The home and ABAC pages both emphasize secure agentic workflows and action-time control.
Multi-tenant and multi-environment policy management
Manage permissions across multiple environments or projects while keeping policy definitions separate. The pricing and model pages describe this as useful for multi-tenancy and environment isolation.
