What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-29, confidence not recorded
A fast, native Rust CLI for browser automation designed specifically for AI agents, communicating with Chrome via CDP through a client-daemon architecture. It returns compact accessibility-tree snapshots with element refs (~200-400 tokens vs thousands for raw DOM), enabling deterministic, token-efficient browser control from any agent that can run shell commands.
Use cases
- automate browser tasks from an AI coding agent like Claude Code or Cursor
- scrape and extract text from web pages with minimal token usage
- fill forms and click elements deterministically via accessibility refs
- take screenshots and record video of headless browser sessions
- test web apps by driving a real browser from the command line
- manage authenticated browser sessions, cookies, and proxies for long-running agents
When to choose
- you need an AI agent to interact with live websites reliably and cheaply in tokens
- you want deterministic element targeting via refs instead of brittle CSS selectors
- you need a fast native binary without Playwright or Node.js runtime dependencies
- you need session persistence, auth state, proxy, and network control for agentic workflows
When to avoid
- you need to automate browsers other than Chromium-based ones
- you want a high-level scripting API in Python or JavaScript rather than a CLI
- your use case is simple HTTP fetching where a headless browser is overkill
- you need pixel-perfect visual regression tooling as the primary feature
