Permio vs Permit.io
Permit.io is a broad authorisation platform: several access models, a no-code policy editor, embeddable UI components and policy decision points you can run yourself. Permio does one thing: roles granted on resource paths, behind a hosted API.
Facts about Permit.io as of October 2026, from its official site and docs (sources below). Corrections welcome.
What Permit.io is
Permit.io describes itself as a way to “add fine-grained authorization to your apps, APIs, and AI agents”, supporting RBAC, ABAC, ReBAC and PBAC through one check API.[1][2] Policies can be edited in a no-code UI or managed as code with Git.[2]
Permit runs a cloud control plane, and decisions are made by a policy decision point (PDP). The managed Cloud PDP evaluates RBAC and ReBAC; the self-hosted Edge PDP container adds ABAC and custom policy-as-code, built on OPA and OPAL.[3] The Edge PDP and OPAL are open source under Apache 2.0.[4][5]
What Permio is
Permio is a hosted permissions API. Resources are paths such as /projects/123/docs/9; you grant roles (bundles of permissions like document.read) to principals or
groups on a path, and the grant covers everything below it. Your backend asks “can this
principal do this here?” and gets allowed or denied. It works alongside whatever login you use.
We’re early: the TypeScript SDK is public on npm, and paid pricing isn’t published yet.
How the models differ
- Breadth vs focus. Permit supports several models and lets you mix them, with OPA underneath.[1][3] Permio has one model, which is less to learn and configure but can’t express attribute rules.
- Deployment. With Permit you choose between the managed Cloud PDP and an Edge PDP you run in your environment, for example to get ABAC.[3] Permio is a hosted API with nothing to deploy.
- Queries. Permit offers check, bulk check, user permissions and authorized users queries.[6] Permio offers Check, BatchCheck, ListAccess and ListPrincipalsWithAccess, and ListAccess is built to become a database filter.
- Platform features. Permit includes embeddable “Elements” for user management and approval flows, decision logs, and an MCP gateway for AI agents.[2][7] Permio includes an Access tester and an audit log, and treats agents as ordinary principals with scoped grants.
At a glance
| Permio | Permit.io | |
|---|---|---|
| Model | Roles and permissions granted on hierarchical resource paths (e.g. /projects/123), inherited by everything below; groups; _ matches one segment | RBAC, ABAC, ReBAC and PBAC; no-code editor or policy-as-code[1][2] |
| Hosting | Managed API hosted by Permio (Google Cloud, London). No self-hosted option today | Cloud control plane; managed Cloud PDP (RBAC, ReBAC) or self-hosted Edge PDP (adds ABAC)[3] |
| Open source | TypeScript SDK (MIT) and Rust client are open source; the service itself is not | Edge PDP, OPAL and SDKs are open source; control plane is not[3][4][5] |
| Queries | listAccess returns scopes you turn into a SQL, Prisma or MongoDB filter; whoHasAccess (ListPrincipalsWithAccess), including members via groups | check, bulk check, user permissions, authorized users[6] |
| SDKs | TypeScript on npm; REST (JSON) and gRPC / gRPC-web for any language; Rust client. Go and Python coming | Node.js, Python, Java, .NET, Go, Ruby, PHP[1] |
| Extras | Dashboard with an Access tester (why a check was allowed) and an audit log of changes | Embeddable Elements, audit and decision logs, MCP gateway[2][7] |
| Pricing | Free to start, no credit card. Paid plans not yet published | Free Community tier with published limits; paid tiers not priced publicly[7] |
When to choose which
Choose Permit.io if
- You need ABAC or several models in one place, or custom policy in OPA.[1][3]
- You need on-premises deployment, compliance attestations such as SOC 2 Type II, or SDKs for Java, .NET, Ruby or PHP.[1][2][7]
- You want embeddable UI for end users, approval workflows, or an MCP gateway today.[2][7]
Choose Permio if
- Your access rules are grants on a hierarchy of resources, and you want inheritance without writing policy.
- You want a small surface: one model, one hosted API, an SDK and a dashboard, with nothing to deploy.
- You want list filtering that turns straight into a database query.
