Kitesurf是Cloudflare出的智能体浏览器，比Chromium省3倍以上CPU和内存，现有Puppeteer加个参数就能用。
Cloudflare发布Kitesurf，这款面向AI智能体的浏览器运行在Cloudflare Workers的V8隔离环境中，底层没有Chromium。Kitesurf用Blitz、Stylo和Boa JS等Rust组件花了12周构建，已通过215,000多项Web Platform Tests。基准测试显示，它在截图和HTML提取任务中比Chromium少用3.1–3.8倍CPU、4.7–7.0倍内存。现有Puppeteer、Playwright和MCP客户端加一个browser=kitesurf参数即可接入，测试期间免费。
Cloudflare Introduces Kitesurf: An Agent-First Web Browser That Runs Entirely in V8 Isolates on Cloudflare Workers
Cloudflare has released Kitesurf, a stateless web browser built specifically for AI agents that runs entirely in V8 isolates on Cloudflare Workers, with no Chromium underneath. The browser drops human-facing features like tabs and extensions in favor of what agents need: machine-readable content, scalability, and isolation. Built in 12 weeks using Rust components like Blitz, Stylo, and Boa JS, it already passes 215,000+ Web Platform Tests. Benchmarks show 3.1–3.8× less CPU and 4.7–7.0× less memory than Chromium on screenshots and HTML extraction. Existing Puppeteer, Playwright, and MCP clients work by adding a single browser=kitesurf parameter, free while in beta.
