Empower your coding agents with advanced browser capabilities.

• Inspect Pages: Gain access to semantic page structure, computed styles, and element details, all condensed for minimal token usage.

• Interact with UI: Enable agents to click buttons, fill forms, scroll pages, and hover over elements, allowing them to drive the browser like a user.

• Capture Logs: Automatically capture and filter console logs, network requests, and JavaScript exceptions for efficient debugging.

• Visual Verification: Capture screenshots to visually verify the agent's work.

DevSnoop operates through a Chrome extension and a native host, allowing any coding agent capable of making HTTP requests to control the browser. Agents send JSON commands to localhost:9400 and receive structured, token-efficient responses, eliminating the need for raw HTML or DevTools protocol.

This tool is compatible with various coding agents including Claude Code, Codex, Cursor, Windsurf, Cline, and Aider, providing a unified way to give your agents 'eyes and hands' on the web.
