## Overview

Permit.io is a full-stack authorization platform that wraps open-source engines (notably Open Policy Agent and OPAL, plus support for relationship-based models) behind a no-code policy UI, SDKs, and a managed control plane. Founded in 2021 and privately held, it aims to give teams a complete authorization layer (policy management, a decision point, and audit) without building one from scratch. Like [Aserto](https://startwithidentity.com/vendors/authorization/aserto/) and [PlainID](https://startwithidentity.com/vendors/authorization/plainid/), it is a policy-management and PDP platform rather than a single raw engine, but it leans more toward startups and developers than the enterprise-heavy positioning of PlainID.

## What it is good at

Breadth of model is the headline: RBAC, ABAC, and ReBAC are all available through one interface, so you can start with simple roles and grow into attributes and relationships without swapping tools. The no-code policy editor lets non-engineers manage access while developers integrate through SDKs in most major languages. Because enforcement runs through a local PDP sidecar (built on OPA/OPAL), decisions stay fast and policy updates distribute in near real time. Onboarding and documentation are developer-friendly.

## Where it falls short

The abstraction is a dependency: you are relying on Permit.io's layer over the underlying engines, and very advanced users may prefer running OPA or a Zanzibar engine directly for full control. Enterprise governance and scale features are still maturing relative to incumbents, and as an authorization-only product it does nothing for authentication, SSO, or MFA.

## Pricing

Free tier for getting started, with usage-based paid plans as you scale monthly active users and policy volume. Confirm current limits on their pricing page, and model real costs with the [TCO calculator](https://startwithidentity.com/tools/tco-calculator/).

## Best for, and who should look elsewhere

Choose Permit.io if you want a managed, multi-model authorization layer with a UI and SDKs and you do not want to operate the engines yourself. If you want a single open-source engine you fully control, look at [OpenFGA](https://startwithidentity.com/vendors/authorization/openfga/) or [Cerbos](https://startwithidentity.com/vendors/authorization/cerbos/); see [OpenFGA vs Cerbos](https://startwithidentity.com/compare/openfga-vs-cerbos/) and the [authorization guide](https://startwithidentity.com/guides/authorization/).

## Bottom line

A strong pick for teams that want authorization delivered as a managed, multi-model layer with a friendly UI rather than a raw engine to run and govern themselves.
