## Documentation

# Deploy and Host Lightpanda Browser on Railway

Lightpanda Browser is a lightweight, headless browser designed for AI agents, web automation, scraping, and testing. It supports the Chrome DevTools Protocol (CDP), making it compatible with popular automation tools such as Playwright and Puppeteer while using an architecture optimized specifically for headless workloads.

## About Hosting Lightpanda Browser

Hosting Lightpanda Browser on Railway gives you a remotely accessible CDP-compatible browser without maintaining a full Chromium-based browser environment yourself. This template runs the official Lightpanda Docker image and starts its CDP server on Railway's assigned port.

Once deployed, you can expose the service through a Railway public domain or connect to it internally using Railway private networking. Your applications, automation workers, or AI agents can then retrieve the browser's CDP WebSocket endpoint and control Lightpanda using Playwright, Puppeteer, or another CDP-compatible client.

No PostgreSQL, Redis, or persistent storage is required for the basic deployment.

## Common Use Cases

* Browser automation with Playwright or Puppeteer
* Web scraping and data extraction
* Browser access for AI agents and automated workflows
* Automated testing for web applications
* Rendering pages for workflows that do not require a graphical browser interface

## Dependencies for Lightpanda Browser Hosting

* Official `lightpanda/browser:latest` Docker image
* A CDP-compatible client such as Playwright, Puppeteer, or another Chrome DevTools Protocol client
* A Railway project with a public domain or private networking, depending on your access requirements

### Implementation Details

This template starts Lightpanda using:

```bash
/bin/sh -c 'exec lightpanda serve --host 0.0.0.0 --port "$PORT"'
```

The service uses:

```env
PORT=9222
```

After deployment, generate a Railway public domain and check the CDP server at:

```text
https://your-lightpanda.up.railway.app/json/version
```

The response includes a `webSocketDebuggerUrl` that can be used by your automation client.

Example with Playwright:

```javascript
import { chromium } from "playwright";

const response = await fetch(
  "https://your-lightpanda.up.railway.app/json/version"
);

const { webSocketDebuggerUrl } = await response.json();

const wsEndpoint = webSocketDebuggerUrl.replace(
  "ws://",
  "wss://"
);

const browser = await chromium.connectOverCDP(wsEndpoint);

const context =
  browser.contexts()[0] ?? await browser.newContext();

const page = await context.newPage();

await page.goto("https://example.com");

console.log(await page.title());

await browser.close();
```

Lightpanda does not provide a traditional browser dashboard. The primary interface is its CDP endpoint.

## Comparison with Traditional Chromium Browsers

Lightpanda and Chromium-based browsers serve different purposes. Lightpanda is optimized for headless automation and programmatic browser access, while Chromium is a more complete browser engine intended to support a broad range of websites and browser features.

### When to Choose Lightpanda

Choose Lightpanda when you need:

* A lightweight remote browser service
* Headless automation through CDP
* Lower resource consumption for large numbers of browser sessions
* A simple Docker-based deployment on Railway
* Browser access for AI agents, scraping, or backend workflows

### When to Choose Chromium

Choose Chromium when you need:

* Maximum compatibility with modern websites
* Advanced browser APIs or features not supported by Lightpanda
* Visual regression testing
* Full browser behavior that closely matches Chrome users
* Support for workflows involving extensions, complex rendering, or broader browser functionality

Lightpanda can be a strong alternative to Chromium for automation workloads, but it should be tested against your target websites and workflows before production use. Some websites may depend on browser features that are available in Chromium but not implemented or fully supported in Lightpanda.
