Kitesurf

Kitesurf is a stateless, highly scalable, and cost-effective headless web browser launched by Cloudflare, designed specifically for AI agents. Running entirely within V8 isolates on Cloudflare Workers, Kitesurf strips away human-centric bloat like tabs, themes, and extensions. Instead, it focuses on the core needs of machine actors—such as HTML extraction, DOM interaction, and screenshot generation. Built with Rust, WebAssembly, and Stylo, it uses 3 to 7 times less CPU and memory than Chromium, significantly reducing infrastructural costs for scaling automated agent workflows.
