An open-source, self-hosted identity and access management platform

Casdoor is a single sign-on (SSO) and authentication server with a web console.
It speaks OAuth 2.0, OIDC, SAML 2.0, CAS, LDAP, SCIM 2.0, WebAuthn, TOTP/MFA and MCP,
and connects to Google Workspace, Microsoft Entra ID (Azure AD), GitHub and many other identity providers.

_{The sign-in page your users see: password, email/SMS code, WebAuthn and Face ID, plus every social provider you enable.}

Admin console. Users, tokens, organizations and providers at a glance.

Applications. Every app that delegates login to Casdoor, across all organizations.

Application settings. OAuth, SAML, providers and branding — no redeploy, no config file.

🚀 Try it in 30 seconds

No database and no config file needed. This runs Casdoor on SQLite with sample data:

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

Open http://localhost:8000 and sign in:

Field	Value
Organization	built-in
Username	admin
Password	123

The sign-in form has separate organization and username fields. Docs sometimes write this pair as built-in/admin — that is the same thing, not a username containing a slash.

Prefer not to install anything? Use the hosted demos:

Demo	URL	Notes
Writable	demo.casdoor.com	Full access, so you can click through everything. All data resets about every 5 minutes.
Read-only	door.casdoor.net	Stable global demo. Every write operation fails by design.

Both accept the same built-in / admin / 123 credentials.

🤔 Why Casdoor

Casdoor is a complete identity provider, not an authentication proxy and not a library you embed. It stores your users, issues the tokens, and gives you an admin console to manage all of it — so your applications can delegate login entirely and never handle a password themselves.

• One server, many protocols. The same user directory is reachable over OAuth 2.0, OIDC, SAML 2.0, CAS, LDAP and SCIM, so a modern SPA and a legacy CAS-only app can share one set of accounts.
• Everything is editable in the UI. Organizations, applications, providers, sign-in methods, email and SMS templates, and login-page branding are configured in the web console instead of in files you have to redeploy.
• Policy-based authorization built in. Access rules are expressed with Casbin — ACL, RBAC, ABAC and custom models — rather than a fixed permission scheme.
• Straightforward to self-host. A single Go binary plus a database. No JVM, no operator, no cluster required.

If all you need is a login screen in front of an existing reverse proxy, a smaller tool may suit you better. Casdoor is for when you want to own the user directory itself.

📦 Installation

Four supported paths, fastest first. All of them end up at http://localhost:8000.

Docker — all-in-one (evaluation)

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

Bundles SQLite and demo data into a single container. Ideal for a first look, but not intended for production: the data lives inside the container and disappears with it.

Guide: Try with Docker

Docker Compose — Casdoor with MySQL

docker-compose.yml starts Casdoor next to a MySQL 8 container.

Two things to know before running it:

1. Compose builds the image from source (Go backend plus React frontend). The first docker compose up takes several minutes, so it is not the quick-trial path — use the all-in-one image above for that.
2. You have to point Casdoor at the bundled database first.

Set the MySQL settings in conf/app.conf to match the db service:

driverName = mysql
dataSourceName = root:123456@tcp(localhost:3306)/
dbName = casdoor

Use localhost here even though MySQL runs in a separate container: the compose file sets RUNNING_IN_DOCKER=true, and Casdoor rewrites localhost to the Docker host address at startup (see conf/conf.go). Then start everything:

docker compose up

The compose entrypoint already passes --createDatabase=true, so the casdoor database is created for you.

Guide: Try with Docker

Kubernetes — Helm

Requires Helm v3 and a running cluster:

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

The chart does not expose Casdoor outside the cluster by default. To reach it, find the service and forward a port:

kubectl get svc

kubectl port-forward svc/<service-name-from-above> 8000:8000

For a real deployment, configure an Ingress and an external database through the chart's values. k8s.yaml in this repo is a minimal plain-manifest example if you would rather not use Helm.

From source — for development

Use this if you intend to modify Casdoor. Prerequisites: Go 1.25+ (see go.mod), Node.js 20 LTS, Yarn 1.x, and a supported database (MySQL, PostgreSQL, SQLite, SQL Server and others).

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

Set driverName, dataSourceName and dbName in conf/app.conf. For MySQL, create the casdoor database first, or start the server with --createDatabase=true. Then build the frontend and run the server:

cd web && yarn install && yarn build && cd .. && go run main.go

While working on the frontend, run yarn start in web/ instead of yarn build to get hot reload on port 7001, with go run main.go serving the API from a second terminal.

Guide: Server installation

👉 After you sign in

At this point you have a running identity provider with nothing connected to it yet. Next:

1. Change the admin password. 123 is a demo credential and must not survive contact with production.
2. Connect your first application — create an Application in the console, copy its Client ID and Client Secret, and point your app's OAuth/OIDC client at Casdoor.
3. Add an identity provider if you want Google, GitHub or Entra ID sign-in.
4. Pick an SDK for your language, or call the Public API directly.

✨ Features

🔒 Security

Please do not report security vulnerabilities in public GitHub issues. Email admin@casdoor.org instead — SECURITY.md has the full policy and disclosure process.

Before exposing a Casdoor instance to the internet:

• Change the built-in admin password. Never ship the demo credential 123.
• Serve Casdoor over HTTPS only, and set origin in conf/app.conf to your public URL.
• Review conf/app.conf for values inherited from the sample file, especially dataSourceName and any provider secrets.
• Set runmode = prod and keep showSql = false in production.
