Cloud browsers for AI agents, scraping, and automation that won't get blocked
Swap launch() for connect() and point your existing Puppeteer or Playwright scripts at a managed cloud browser — no rewrite required.
Give MCP clients like Claude or Cursor ready-made search, scrape, and crawl tools, or run Browserless's own stateful agent for multi-step tasks.
Automatic anti-bot bypass, built-in CAPTCHA solving, and residential or datacenter proxy rotation to get through blocked targets.
Log in one time and reuse the session across every run, so agents start signed in without credentials baked into your code.
