Deploy and Host Chromium Browser on Railway

Chromium Browser provides a private, browser-based Chromium desktop that you can access remotely from anywhere. This template uses the LinuxServer Chromium container with persistent storage, authentication, and additional shared memory for a smoother browser experience.

About Hosting Chromium Browser

This template deploys Chromium as a remote web browser that runs entirely inside your Railway project.

Instead of installing Chromium on your local device, you access the browser through a normal web page. The actual Chromium session runs in the container, while the interface is streamed securely to your browser.

A persistent volume stores the Chromium profile and configuration so bookmarks, browser preferences, cookies, extensions, and other profile data can survive restarts and redeployments.

The template also includes authentication to prevent unrestricted public access to the remote browser.

Included Architecture

Common Use Cases

Access a private Chromium browser from anywhere
Run a persistent browser in the cloud
Keep bookmarks and browser settings available across devices
Use a remote browser for development and testing
Test websites from a remote environment
Access browser-based administration tools
Run browser extensions on a persistent remote profile
Separate a dedicated browser environment from your local machine
Provide a browser workspace for temporary or remote access
Use Chromium from devices where installing a desktop browser is impractical

Chromium Browser vs Local Browser

Feature	Chromium Browser	Local Chromium
Runs remotely	✅ Yes	❌ No
Browser-based access	✅ Yes	❌ Native application
Persistent profile	✅ Yes	✅ Yes
Accessible from multiple devices	✅ Yes	⚠️ Requires sync
Infrastructure control	✅ Yes	✅ Local device
Dedicated environment	✅ Yes	⚠️ Shares local system
No local installation required	✅ Yes	❌ Installation required

This setup is especially useful when you want a dedicated browser environment that remains available independently of your local computer.

Persistent Storage

The Chromium service stores persistent configuration under:

/config

The persistent volume can retain:

Chromium profile
Browser settings
Bookmarks
Cookies
Extensions
Session configuration
Local browser files
LinuxServer application settings

Without persistent storage, browser configuration would be lost whenever the container is recreated.

Authentication

The remote browser is protected using credentials configured by the template.

After deployment, open the Chromium service Variables page and use:

CUSTOM_USER
PASSWORD

to access the web interface.

Because this service exposes a fully functional remote browser, authentication should always remain enabled when the application is publicly accessible.

Getting Started

Deploy Chromium Browser.
Wait until the Chromium service is online.
Open the public Railway domain assigned to the service.
Sign in using the configured username and password.
Wait for the Chromium desktop session to load.
Start browsing.
Customize Chromium settings, bookmarks, and extensions as needed.

Your browser profile is stored persistently and remains available after service restarts or redeployments.

Browser Performance

Chromium uses shared memory for browser processes, rendering, and complex web applications.

This template allocates additional shared memory compared with the default Railway container configuration to improve stability when running:

Multiple browser tabs
Video playback
JavaScript-heavy applications
Development dashboards
Large web applications
Browser extensions

Resource requirements will still depend on the websites and number of tabs being used.

For heavier workloads, increase the Railway service memory and CPU allocation as needed.

Public Networking

The Chromium web interface listens on:

Railway terminates HTTPS at its public proxy and forwards traffic internally to the Chromium service.

Internet
    │
    │ HTTPS
    ▼
Railway Proxy
    │
    │ HTTP
    ▼
Chromium :3000

The container's additional internal HTTPS port is not required for the standard Railway deployment.

Security Considerations

A remote browser can access websites, authenticated sessions, cookies, and potentially sensitive information.

For production or personal use:

Keep the browser access password private.
Use a strong authentication password.
Avoid sharing the public Chromium URL.
Keep persistent browser sessions in mind when accessing sensitive websites.
Sign out of important services when the browser is shared.
Review installed extensions carefully.
Avoid exposing the service without authentication.
Treat the persistent /config volume as sensitive data.

If the Chromium instance is no longer needed, remove stored sessions or delete the persistent volume when appropriate.

Why Deploy Chromium Browser on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Chromium Browser on Railway, you get a private remote browser with persistent profile storage, authentication, HTTPS access, and additional shared memory in a simple one-click deployment.
