// como funciona

Como funciona

  1. Decide local or cloud

    Use your local browser for logged-in, personal work; Browser Use Cloud is for running many browsers in parallel.

  2. Get the harness

    Paste the README's setup prompt into Claude Code or Codex and let the agent install it.

  3. Connect your browser

    Enable remote debugging at chrome://inspect so the agent can attach over CDP.

  4. Run your first task

    Give the agent a real browser task and watch it write any missing helpers on the fly.

Por que as pessoas gostam tanto

Direct CDP connection

Talks to your real browser through one editable CDP websocket - no separate automation browser profile required.

Self-healing helpers

When a capability is missing, the agent writes a reusable helper into its workspace, so repeat tasks get faster.

Skill-driven workflow

A SKILL.md teaches the agent the browser workflow; install.md handles connection setup.

MCP server included

browser-harness-mcp exposes the browser-control helpers as MCP tools over stdio for Claude Code, Devin, Cursor and other clients.

Works with your logins

Because it drives your real browser, tasks can use your existing logged-in sessions.

Cloud scaling path

Scale out with Browser Use Cloud for parallel browsers with live previews, proxies and stealth when local is not enough.

Execute você mesmo

  1. Clone the repository

    Get the source code from GitHub and enter the project directory.

    git clone https://github.com/browser-use/browser-harness.git
    cd browser-harness
  2. Install via the setup prompt

    The README's recommended route is pasting its setup prompt into your coding agent; it installs with uv on Python 3.12 and registers the skill.

    # Paste the Setup prompt from the README into Claude Code or Codex
  3. Connect the browser

    The agent opens the remote-debugging settings page; tick the checkbox so it can connect.

    # Open chrome://inspect/#remote-debugging and enable the connection as the README shows

Perguntas frequentes

Who maintains this project?

It is maintained by the Browser Use team (browser-use) on GitHub.

Is it free to use?

Yes - Browser Harness is MIT licensed and free for local use. Browser Use Cloud is a separate paid service for scaling.

Does it need a paid API key?

You need an LLM agent (for example Claude Code or Codex) with its own model access; the local harness itself has no API fee.

How does it compare to alternatives?

Compared with Playwright scripts, the harness is agent-driven and self-healing - it writes missing helpers instead of failing - and it drives your real browser rather than a fresh automation profile.

How do I get started?

Paste the README's setup prompt into Claude Code or Codex, enable remote debugging when asked, and assign a small task.
