Cloudflare launched Kitesurf, a cloud-hosted browser built for AI agents rather than people, TechCrunch reported Friday.
Kitesurf runs on Cloudflare's serverless Workers platform and is assembled from parts: the modular Blitz rendering engine, Firefox's Stylo CSS parser and Boa, a JavaScript engine written in Rust. The team built it in 12 weeks, according to TechCrunch.
Because no human looks at it, the browser skips themes, tabs and rendering polish. It optimizes instead for context windows, token costs, performance and scale, and Cloudflare said it uses less computing power than Chromium for common automation tasks. It currently passes more than 215,000 web platform tests and renders sites including Wikipedia and Hacker News.
Kitesurf is free during beta through Browser Run, Cloudflare's headless browser service.
Purpose-built agent browsers are becoming a category: as agents move from answering questions to completing tasks, the browser bill becomes an infrastructure cost, and vendors are competing to shrink it.
