About DevSnoop
What is DevSnoop?
DevSnoop is a browser automation and inspection tool for coding agents. It pairs a Chrome extension with a local native host to give AI agents access to live browser tabs.
What DevSnoop does
DevSnoop lets coding agents such as Codex and Claude Code inspect local Chrome tabs, click UI elements, fill forms, and take screenshots. The tool captures console logs, exceptions, and network errors, while measuring text legibility. It pairs a Chrome extension with a native host on the machine, exposing browser inspection, compact page summaries, reusable selectors, and lightweight DOM diffs through an HTTP API.
Who DevSnoop is for
It is built for software engineers and developers using autonomous coding agents to build and verify web applications.
How DevSnoop works
Users install the Chrome extension and start the native host on their machine. Coding agents read commands from a SKILL.md file and interact with open browser tabs through a local HTTP server.
