Developers running agents that read lots of pages can cut compute costs here while it's free in beta, accepting slower page loads.
Kenning's take
What it does
Kitesurf is a stateless browser built by Cloudflare for AI agents, running on Cloudflare Workers rather than shipping a full Chromium engine. Cloudflare's tests show it uses 3 to 7 times less CPU and memory than Chromium for screenshots and page extraction, though it is slower in wall-clock time. It is in beta inside Cloudflare Browser Run, free during the beta, and works with Puppeteer, Playwright and other DevTools Protocol clients.
