Deploy and Host Kernel Browser on Railway

Kernel Browser is a cloud-native, sandboxed Chromium environment built for browser automation and AI agents. It exposes a REST API for screen recording, screenshots, keyboard/mouse control, file system access, and process execution — all backed by a full X11 desktop with Chrome DevTools Protocol support.

About Hosting Kernel Browser

Deploying Kernel Browser involves running a multi-service Docker container that orchestrates Xorg, Mutter (window manager), D-Bus, Chromium, and a Go-based API server via Supervisord. The container starts a virtual display, launches a headful Chromium instance with remote debugging enabled, and exposes two network interfaces: a REST API on port 10001 for automation commands and a WebSocket proxy on port 9222 for direct Chrome DevTools Protocol access. The image requires running as root with --no-sandbox and --disable-dev-shm-usage flags due to container constraints. A health check on /spec.yaml confirms full stack readiness.

Common Use Cases

Running AI agent workflows that need a real browser environment (web scraping, form filling, testing)
Capturing video recordings and screenshots of automated browser sessions
Providing a remote Chromium instance with DevTools Protocol access for Playwright or Puppeteer automation

Dependencies for Kernel Browser Hosting

Docker (multi-stage build with Go, Node.js, Ubuntu 22.04 base)
Minimum 2 GB RAM (Chromium + X11 + API server)
