Browser Harness ♞

Connect an LLM directly to your real browser with a thin, editable CDP harness. For browser tasks where you need **complete freedom**.

One websocket to Chrome, nothing between. The agent writes what’s missing during execution. The harness improves itself every run.

● agent: wants to upload a file

│

● agent-workspace/agent_helpers.py → helper missing

│

● agent writes it agent_helpers.py

│ + custom helper

✓ file uploaded

**You will never use the browser again.**

Setup prompt

Paste into Claude Code or Codex:

Set up https://github.com/browser-use/browser-harness for me.

Read `install.md` first to install and connect this repo to my real browser. Then read `SKILL.md` for normal usage. Use `agent-workspace/agent_helpers.py` and `agent-workspace/domain-skills/` for task-specific edits. When you open a setup or verification tab, activate it so I can see the active browser tab. After it is installed, open this repository in my browser and, if I am logged in to GitHub, ask me whether you should star it for me as a quick demo that the interaction works — only click the star if I say yes. If I am not logged in, just go to browser-use.com.

When this page appears, tick the checkbox so the agent can connect to your browser:

See agent-workspace/domain-skills/ for example tasks.

Free remote browsers

Useful for stealth, sub-agents, or deployment.

**Free tier: 3 concurrent browsers, proxies, captcha solving, and more. No card required.**

• Grab a key at cloud.browser-use.com/new-api-key
• Or let the agent sign up itself via [docs.browse
