Authorizer

Authorizer is an open-source authentication and authorization solution for your applications. Bring your database and have complete control over the user information. You can self-host authorizer instances and connect to any database (Currently supports 11+ databases including Postgres, MySQL, SQLite, SQLServer, YugaByte, MariaDB, PlanetScale, CassandraDB, ScyllaDB, MongoDB, ArangoDB).

For more information check:

• Migration Guide (v1 → v2) – configuration changes, CLI flags, deprecated APIs
• Docs (v1 – legacy)
• Discord Community
• Contributing Guide

v2 note: Authorizer v2 uses CLI arguments for all configuration. The server does not read from .env or OS env. Pass config when starting the binary (e.g. ./authorizer --client-id=... --client-secret=...). See MIGRATION.md.

Deploy Authorizer Using Source Code

This guide helps you practice using Authorizer to evaluate it before you use it in a production environment. It includes instructions for installing the Authorizer server in local or standalone mode.

Prerequisites

• OS: Linux or macOS or Windows
• Go >= 1.24 (see go.mod)
• Node.js >= 18 and npm (only if building the web app and dashboard)

Project Setup

1. Fork the authorizer repository (Skip this step if you have access to repo)
2. Clone repo: git clone https://github.com/authorizerdev/authorizer.git or use the forked url from step 1
3. Change directory: cd authorizer
4. Build the server binary: make build (or go build -o build/authorizer .)
5. (Optional) Build the web app and dashboard: make build-app and make build-dashboard
6. Run the server with CLI arguments:

 make dev

Or run manually with your config:

v2: The server does not read from .env. All configuration must be passed as CLI arguments. See MIGRATION.md for the full mapping of env vars to flags.

Run with Docker

Run Authorizer with SQLite using the official image (replace with your own image if you build from source):

docker run -p 8080:8080 \
  -v authorizer_data:/authorizer/data \
  lakhansamani/authorizer \
  --database-type=sqlite \
  --database-url=/authorizer/data/data.db \
  --client-id=123456 \
  --client-secret=secret \
  --admin-secret=admin \
  --jwt-type=HS256 \
  --jwt-secret=test

• Port 8080 serves the app and GraphQL; use -p 8080:8080 to expose it.
• Volume authorizer_data persists the SQLite DB; use a named volume or a host path (e.g. -v $(pwd)/data:/authorizer/data).
• All config is passed as CLI arguments (the image uses ENTRYPOINT ["./authorizer"] so args after the image name go to the binary). See MIGRATION.md for the full list of flags.

Extending the image with env-based config (e.g. Railway): If you FROM lakhansamani/authorizer and use a shell-form CMD so that env vars are expanded at runtime, you must override ENTRYPOINT in your Dockerfile or the binary will receive /bin/sh and -c as arguments and fail. Use:

FROM lakhansamani/authorizer:2.0.0-rc.1
# v2 uses CLI arguments only. Railway (etc.) inject env vars; shell form CMD expands them at runtime.
# Override ENTRYPOINT so CMD is run by a shell; otherwise the base ENTRYPOINT would receive /bin/sh -c "..." as args.
ENTRYPOINT ["/bin/sh", "-c"]
CMD ./authorizer \
  --database-type="$${DATABASE_TYPE:-postgres}" \
  --database-url="$${DATABASE_URL}" \
  --client-id="$${CLIENT_ID}" \
  --client-secret="$${CLIENT_SECRET}" \
  --admin-secret="$${ADMIN_SECRET}" \
  ...

Use $$ in the Dockerfile so Docker does not expand $VAR at build time.

Deploy Authorizer using binaries

Deploy / Try Authorizer using binaries. With each Authorizer Release, binaries are baked with required deployment files and bundled. You can download a specific version for the following operating systems:

• macOS (amd64, arm64)
• Linux (amd64, arm64)

Download and unzip bundle

• Download the bundle for your OS/arch from the release page

Note: For Windows, we recommend running Authorizer via Docker.

• Unzip (Mac / Linux):

  tar -zxf authorizer-VERSION-OS-ARCH.tar.gz
  cd authorizer-VERSION-OS-ARCH

Start Authorizer

• Run the binary with required CLI arguments:

  ./authorizer \
    --database-type=sqlite \
    --database-url=data.db \
    --client-id=YOUR_CLIENT_ID \
    --client-secret=YOUR_CLIENT_SECRET \
    --admin-secret=your-admin-secret

v2: The binary is named authorizer (not server). Configuration is passed via CLI arguments; .env is not read. On macOS you may need: xattr -d com.apple.quarantine authorizer

Step 2: Setup Instance

• Open the Authorizer instance endpoint in your browser
• Sign in as admin using the --admin-secret you configured at startup

v2: Environment variables are not configurable from the dashboard. All configuration is set at startup via CLI arguments. See MIGRATION.md for the full list of flags.

Things to consider

• For social logins, you will need respective social platform key and secret
• For having verified users, you will need an SMTP server with an email address and password using which system can send emails. The system will send a verification link to an email address. Once an email is verified then, only able to access it.

  Note: One can always disable the email verification to allow open sign up, which is not recommended for production as anyone can use anyone's email address 😅

• For persisting user sessions, you will need Redis URL (not in case of railway app). If you do not configure a Redis server, sessions will be persisted until the instance is up or not restarted. For better response time on authorization requests/middleware, we recommend deploying Redis on the same infra/network as your authorizer server.

Testing

Integrating into your website

This example demonstrates how you can use [@authorizerdev/authorizer-js](/authorizer-js/getting-started) CDN version and have login ready for your site in few seconds. You can also use the ES module version of [@authorizerdev/authorizer-js](/authorizer-js/getting-started) or framework-specific versions like [@authorizerdev/authorizer-react](/authorizer-react/getting-started)

Copy the following code in html file

Note: Change AUTHORIZER_URL in the below code with your authorizer URL. Also, you can change the logout button component

<script src="https://unpkg.com/@authorizerdev/authorizer-js/lib/authorizer.min.js"></script>

<script type="text/javascript">
	const authorizerRef = new authorizerdev.Authorizer({
		authorizerURL: `YOUR_AUTHORIZER_INSTANCE_URL`,
		redirectURL: window.location.origin,
		clientID: 'YOUR_CLIENT_ID', // obtain your client id from authorizer dashboard
	});

	// use the button selector as per your application
	const logoutBtn = document.getElementById('logout');
	logoutBtn.addEventListener('click', async function () {
		await authorizerRef.logout();
		window.location.href = '/';
	});

	async function onLoad() {
		const res = await authorizerRef.authorize({
			response_type: 'code',
			use_refresh_token: false,
		});
		if (res && res.access_token) {
			// you can use user information here, eg:
			const user = await authorizerRef.getProfile({
				Authorization: `Bearer ${res.access_token}`,
			});
			const userSection = document.getElementById('user');
			const logoutSection = document.getElementById('logout-section');
			logoutSection.classList.toggle('hide');
			userSection.innerHTML = `Welcome, ${user.email}`;
		}
	}
	onLoad();
</script>
