Other Code Examples

Find an open-source example repository that shows Permit.io authorization in the framework, language, or stack you use. This page is for developers who want working code to read or copy before they add permission checks to their own app. For guided walkthroughs of full demo apps, see the other pages in this section, such as Food Delivery System Example.

What the examples cover

Each repository is a runnable app or integration maintained in the permitio GitHub organization. The examples show how to:

• Call permit.check() from a backend framework or middleware.
• Model role-based access control (RBAC), attribute-based access control (ABAC), and relationship-based access control (ReBAC) policies, and sync users, resources, and relationships to Permit.
• Show or hide frontend features with the permit-fe-sdk and CASL.
• Run the policy decision point (PDP) on different platforms.
• Manage policy as code with GitOps, Open Policy Agent (OPA) Rego, and the Open Policy Administration Layer (OPAL).
• Add permission checks to AI agents and retrieval pipelines.

Typical topics in the list:

Topic	Examples of what you find
Backend frameworks	Express, Fastify, FastAPI, Spring Boot, Go, and Java apps that call permit.check()
Frontend frameworks	React, Angular, and Vue apps that toggle UI with permit-fe-sdk and CASL
Full demo apps	Galactic Health Corporation, Pink Mobile, the Nuxt food delivery app, the Mesa Verde banking demo, Fleet Ops, the Great Eagle Logistics portal, and fine-grained bot protection, in the permitio/examples repository
Deployment	PDP deployment examples for different platforms
Policy as code	Example OPAL policy repositories, generated policy code, and Rego-based ReBAC
AI agents	LangChain, Langflow, and PydanticAI integrations

Full demo apps in the examples repository

The permitio/examples repository holds full demo apps, one per folder, including the seven below. Each of these folders runs with Docker Compose and a local PDP, needs only a Permit environment API key, and has a README with the steps:

Folder	What it shows	Walkthrough
galactic-health-corporation	A healthcare portal with caregiver delegation, member groups, and pilot groups	Healthcare Demo Application
pink-mobile	A mobile plan app with manager, representative, and customer personas	Teleco Demo Application
nuxt-food-delivery	A multi-city food delivery app with RBAC, ABAC, and ReBAC on the same actions	Food Delivery System Example
mesa-verde-banking	A banking app with multi-tenant RBAC, wire transfer rules, and approval flows	Banking app example: Mesa Verde
fleet-ops-demo	A multi-tenant fleet app on the Go SDK with nested organizations, partner access, attribute-based sets, custom Rego rules loaded through GitOps, and Terraform for the schema	Multi-tenant fleet example: Fleet Ops
permit-portal-demo	A logistics business portal with onboarding approvals, time-boxed collaborator access, and a panel that shows each Permit check and write	Logistics portal example: Great Eagle
fine-grained-bot-protection	An Express app that gives humans and bots different access, with ABAC on a botType user attribute	Bot protection example: humans and AI bots

Browse the example repositories

The following list loads in your browser from the GitHub search API. The list includes every non-archived repository in the permitio organization that has the example topic, sorted by the most recently updated. Each card links to the repository and shows its GitHub description. To search the same set on GitHub, open permitio repositories with the example topic. If the list stays empty, the GitHub search API may have rate-limited unauthenticated requests from your network. Use the GitHub search link instead.

Next steps

• Healthcare Demo Application walks through RBAC, ABAC, and ReBAC in one Next.js app.
• Teleco Demo Application shows a policy model built with the Node.js SDK.
• Check permissions with permit.check() covers the check call used in every example.
