# Cloudflare Launches Kitesurf: Agent-First Browser 7x More Efficient Than Chromium

> Cloudflare has released Kitesurf, a browser with an unusual target user: no human ever looks at it. It is built to be driven by AI agents, the software that books flights, fills forms, and clicks through websites on your behalf, and Cloudflare says it uses three to seven times less memory and CPU than Chromium on those tasks. The engineering story is the interesting part. Rather than fork Chrome, the team assembled Kitesurf in about twelve weeks from modular open pieces, the Blitz renderer, Firefox's Stylo CSS engine, and the Boa JavaScript engine, all written in Rust and running on Cloudflare's Workers platform. It already passes more than 215,000 web platform tests, and it is free in beta through Cloudflare's Browser Run service. Why it matters: today's agents mostly puppet a full desktop Chrome, which is wildly wasteful when there is no screen to paint. As agent traffic grows, purpose-built browsers like this could quietly become core infrastructure, and Cloudflare clearly wants to own that layer.
