## Why Casdoor

Casdoor is a **UI-first** identity provider and access management platform: one place to manage users, organizations, applications, and providers, with a modern web console. Authorization policies can be expressed with **[Casbin](https://casbin.org/)** (ACL, RBAC, ABAC, and more). Unlike reverse-proxy-centric auth companions, Casdoor is a dedicated auth server with broad protocol support, designed to be straightforward to self-host and integrate—see **[casdoor.ai](https://casdoor.ai)** for documentation.

<a id="live-demos"></a>
## 🌐 Live demos

| Environment | URL | Description |
|-------------|-----|-------------|
| **Read-only** | [door.casdoor.com](https://door.casdoor.com) | Global demo; **any modification or write operation will fail** (read-only). |
| **Writable** | [demo.casdoor.com](https://demo.casdoor.com) | Full access for testing; **data is reset about every 5 minutes**. |

Default demo admin login (where applicable): `admin` / `123` — use only for demos; change credentials on your own deployment.

<a id="quick-start"></a>
## 🚀 Quick start

Pick one deployment method below. To keep behavior consistent with upstream, the steps are aligned with official docs.

### 🛠️ Source code (default)

1. Install dependencies: **Go 1.25** (follow `go.mod`), **Node.js LTS (20)**, **Yarn 1.x**, and a supported database.
2. Clone the repository:

```bash
git clone https://github.com/casdoor/casdoor.git
cd casdoor
```

3. Configure database in `conf/app.conf` (at minimum set `driverName`, `dataSourceName`, and `dbName`; for MySQL create database `casdoor` first).
4. Build frontend and start backend:

```bash
cd web
yarn install
yarn build
cd ..
go run main.go
```

5. Open [http://localhost:8000](http://localhost:8000) and sign in with `built-in/admin` / `123` on a fresh install (change password immediately in production).

Official guide: [Server installation](https://casdoor.ai/docs/basic/server-installation)

### 🐳 Docker

Use one of the official Docker paths:

- **All-in-one (SQLite quick trial)**:

```bash
docker run -p 8000:8000 casbin/casdoor-all-in-one
```

- **Docker Compose** (with your `conf/app.conf` next to `docker-compose.yml`):

```bash
docker compose up
```

Then open [http://localhost:8000](http://localhost:8000) and sign in with `built-in/admin` / `123` on a fresh install.

Official guide: [Try with Docker](https://casdoor.ai/docs/basic/try-with-docker)

### ☸️ Kubernetes Helm

With Helm v3 and a running Kubernetes cluster:

```bash
helm install casdoor oci://registry-1.docker.io/casbin/casdoor-helm-charts
```

After installation, access Casdoor through your cluster service/ingress. The official guide covers chart versions (including optional `--version`) and cluster-specific settings.
