Cloudflare推出了Kitesurf，一款专为AI Agent设计的浏览器产品，运行在V8隔离环境中[1]。该浏览器基于Cloudflare Workers平台构建，采用Rust编写并编译为WebAssembly在Workers中运行[1]。相比传统Chromium，Kitesurf在内存和CPU消耗上降低了3至7倍[1]。
Kitesurf已通过215000多项Web平台测试，支持Chrome DevTools Protocol协议，兼容Puppeteer和Playwright等开发工具[1]。该项目从5月首次提交以来，仅用12周时间完成开发[1]。目前Kitesurf作为Browser Run产品的免费测试版本提供，Cloudflare计划将其开源[1]。
Cloudflare has launched Kitesurf, a lightweight browser purpose-built for AI agents that operates within V8 isolates on the Cloudflare Workers platform [1]. The browser is written in Rust and compiled to WebAssembly to run in the Workers environment [1]. Compared to Chromium, Kitesurf reduces memory and CPU consumption by 3-7 times [1]. The project achieved this performance through a focused development cycle, with its first commit in May and completion in just 12 weeks [1].
The browser has been validated against over 215,000 Web Platform Tests [1]. Kitesurf supports the Chrome DevTools Protocol (CDP), making it compatible with automation tools like Puppeteer and Playwright [1]. Currently offered as a free beta version under the Browser Run product, Cloudflare plans to open-source Kitesurf in the future [1].
