GDD - AI-Controlled Browser Farm
Runs a local fleet of isolated Chromium instances that Claude can orchestrate through 36 MCP tools. You get parallel browser control across 22 device profiles (iPhone 15 Pro, Desktop 1080p, etc.), each with separate cookies, console access, and network conditions. The tools cover navigation, element interaction (tap, type, scroll), screenshots, console log extraction, and device emulation. Think testing a responsive signup flow on three phones and a desktop simultaneously, or scraping content that requires different geolocations and user agents. Connects via HTTP on localhost:9700, so it works with Claude Code, Cursor, and VS Code based IDEs. Available as standalone binaries for Linux, macOS, Windows, or a Docker image with Chromium pre installed.
