Cloudflare Launches Kitesurf Browser Optimized for AI Agents

Cloudflare has introduced Kitesurf, a lightweight headless browser designed specifically for AI agents, currently available in beta through the company's Browser Run platform.

Internal tests show Kitesurf uses 3.1 to 3.8 times less CPU and 4.7 to seven times less memory than standard Chromium browsers, though task completion times are 1.7 to 1.8 times longer.

Built on Cloudflare Workers, the browser features built-in page isolation to prevent data leaks and is compatible with existing automation libraries like Puppeteer and Playwright.
