ChainThink reports that on August 7, Cloudflare launched the browser engine Kitesurf for AI agents, eliminating dependence on Chromium and enabling direct execution on Cloudflare Workers. It is currently available in testing, with plans to open-source it in the future.
Cloudflare believes that an agent does not require traditional browser features such as tabs, themes, or extensions, nor does it aim for pixel-perfect webpage rendering, as launching a full Chromium instance would consume significant computational power and memory.
Testing shows that Kitesurf uses approximately one-third the CPU and as little as one-seventh the memory of Chromium;
However, task completion time increases by approximately 70% to 80%, with the main advantage being resource savings and support for running more agents simultaneously.
Kitesurf has integrated with Cloudflare Browser Run, supporting Puppeteer, Playwright, MCP, and CDP calls, free during the testing period;
Video, WebGL, some anti-bot verification, and long-term login sessions are not yet supported; complex web pages still require Chromium.
