Browser Use

Browser Use has become one of the best-known open-source projects for letting AI models operate a real web browser, and the company built a hosted platform around that library. Developers can start with the free code on their own machines, then move to managed agents or cloud browsers when they need scale, reliability or protection against blocking.

• The open-source library is MIT licensed and, according to the site, counts well over a hundred thousand GitHub stars.
• Hosted Browser Use Agents accept a task in plain language and return the finished result.
• Cloud browsers connect through Playwright or Puppeteer over CDP, and the company reports strong results on bot-protected pages in its own testing.
• Browser Harness lets coding agents like Claude Code, Codex or Cursor work inside your actual Chrome profile.
• Pay-as-you-go billing charges for browser hours, proxy traffic and model tokens, with a free starter credit and no expiry on credits.

Browser Use is best for developers and AI engineers building agents that need to act on websites without official APIs. A practical tip: prototype locally with the open-source library first to tune prompts and task steps, then switch to cloud browsers once you hit sites with bot detection or need many sessions running in parallel.
