PyPI: browser-use 0.13.14 (checked 2026-10-27); requires Python >=3.11,<4.0; classifier License :: OSI Approved :: MIT License
GitHub: browser-use/browser-use — MIT — ~119,222 stars — pushed 2026-10-27T00:02:24Z — description: "Open-source Python library for AI browser agents, plus Browser Use Cloud: stealth browsers and a hosted agent API."

README (main, raw.githubusercontent.com/.../README.md), key quotable claims:
1. "The open-source browser agent. Run it locally with any LLM, or on Browser Use Cloud: stealth browsers from $0.02/hour..."
2. Path 3 Python Library install: `uv add browser-use` (Python >= 3.11)
3. Example uses Agent(task=..., llm=ChatOpenAI(...)) then history = await agent.run(); print(history.final_result())
4. FAQ "Can I use this for free?": "The Python library is free and MIT-licensed. Model inference and hosted browsers are separate: API providers, including ChatBrowserUse, and Browser Use Cloud charge for usage. You can also use a local browser and a local model through Ollama..."
5. Supported models docs: native ChatOpenRouter example — from browser_use import Agent, ChatOpenRouter; llm = ChatOpenRouter(model="..."); OPENROUTER_API_KEY required.
6. Browser config docs: Browser(headless=..., window_size=...) for a local browser.

Pricing (library vs cloud), checked_on 2026-10-27:
- Open-source library: free (MIT), no account for the library itself.
- Model inference: bring your own key (we use free OpenRouter models only).
- Browser Use Cloud (not tested today): hosted browsers from $0.02/browser-hour; new signups get $1 cloud credit (README). We do NOT use Cloud or BROWSER_USE_API_KEY in this test.

What we are NOT testing (cloud / paid): stealth browsers, CAPTCHA solving, residential proxies, ChatBrowserUse / BU2 model, fully hosted Cloud Agent API.
