Browser Use

Open-source Python framework that lets LLM agents see and control a real browser to complete multi-step web tasks without brittle selectors.

Browser Use was founded in 2024 by Magnus Muller and Gregor Zunic, who met while studying data science and built the first version through ETH Zurich's Student Project House. The open-source library gives an LLM agent control over a real browser session, converting the page into a structured representation the model can reason over so it can click, type, and navigate the way a person would, rather than depending on hand-written CSS or XPath selectors. The GitHub repository grew past 50,000 stars within months of release, becoming one of the fastest-growing open-source AI projects of the past two years, with contributions from thousands of developers building web-browsing agents, scrapers, and QA tools on top of it. The company also runs Browser Use Cloud, a hosted version that manages browser sessions, proxies, and CAPTCHA handling so teams don't have to operate their own headless browser infrastructure. Browser Use raised a $17 million seed round in March 2025 led by Felicis Ventures, with Y Combinator and Nexus Venture Partners also participating. The small team, based in San Francisco, competes with Skyvern, Stagehand, and traditional frameworks like Playwright and Puppeteer for developers building agentic web automation.
