Everything a GUI browser gives you — page rendering, cookie management, DevTools operations (Network / Console / Elements) — is available as `kb` commands. FoxyProxy-style proxy profiles are built in, with **restart-free switching** and per-host routing rules. Designed to be driven by AI agents (Claude Code, etc.) via Bash or MCP, while the window is a real Chrome you can use by hand at any time.

**Two workflows it's built for:**

Drive it from an AI agent — Claude Code and other agents operate kb over MCP (34 tools) or Bash (every command supports JSON action results). The accessibility-snapshot + --ref loop is tuned for reliable, low-token automation, and the resident daemon returns each step in tens of milliseconds.

Features

Daemon architecture — the browser stays resident; every CLI command returns in tens of milliseconds
Uses installed Chrome/Edge — prefers a real browser with DRM support and falls back to bundled Chromium
