What it is
Browser Use is a Python library that connects a language model to a web browser so an AI agent can click, type, and navigate pages to finish a task you describe in plain language. You can run it locally with your choice of model, or use a cloud browser service from the same project. The README's example task is looking up a repository's star count, and a demo shows the agent booking a driving test.
- Ask an agent to look up information on a website and print the result
- Automate a multi-step web booking or form submission from a task description
- Run the same agent code on a local browser or a cloud browser by changing one parameter
Great for
- Python developers who want to prototype an AI agent that operates websites
- Teams automating repetitive multi-step web tasks such as lookups or form filling
- People who want to run the agent locally with their own LLM API key
- Users who need a cloud browser for environments without Chrome, such as Docker or CI
Not ideal for
- Non-programmers who want a no-code tool; the README's main path is Python code or an agent prompt
- Projects needing fully deterministic scripts, since the agent's behavior depends on a language model
- Anyone unwilling to pay for cloud browsers or manage API keys for the hosted options
How to get it
- 1
Install with a package manager
You'll need: Python 3.11 or newer · uv package manager · OpenAI API key or another supported LLM key
Install the library with uv
uv add browser-use - 2
Run it
- Add your OpenAI API key to a .env file
- Save the example code as agent.py
- Run uv run agent.py to start the agent
- Optionally set BROWSER_USE_API_KEY and enable the cloud browser line
- 3
Get the most out of it
- Switch to the BU2 model by using the ChatBrowserUse line in the example, which requires BROWSER_USE_API_KEY
- Use Browser(use_cloud=True) to run on a cloud browser without installing Chrome locally
- Consult the Python library docs at docs.browser-use.com for further options
Downloads
Strengths
- Works with a chosen LLM provider, and the README shows OpenAI as an example
- Same agent code runs locally or on a cloud browser with a single change
- MIT licensed and actively pushed
Trade-offs
- Depends on a paid or API-keyed language model and, for cloud features, a Browser Use API key
- Cloud browser pricing and hosted features are described by the vendor and sit outside the open-source code
- The README is truncated, so some details of setup and configuration are not confirmed here
