TL;DR Cloudflare launched Kitesurf, an agent-first browser on Workers. Cloudflare built a browser from scratch for AI agents and launched it today as a free beta inside its Browser Run product. What remains is a lightweight engine optimised for the things agents actually care about, structured content extraction, screenshots, and isolation between sessions. That surge is exactly why Cloudflare decided a Chromium-based headless browser, built for humans and repurposed for machines, was no longer the right tool. Cloudflare is simultaneously blocking AI crawlers that harvest content without paying, while building the infrastructure for agents that do pay.
