Cloudflare Open-Sources Its AI Agent Browser Kitesurf

In August, Cloudflare launched Kitesurf, a browser made for AI agents. The company has now open-sourced it, and the code is hosted on GitHub.

Kitesurf runs on Cloudflare Workers. It can parse HTML, apply CSS, run JavaScript, and take webpage screenshots without a browser container. It also supports Chrome DevTools Protocol and needs no Chromium process.

The browser focuses on what agents care about most, like token use, context window and scalability, while dropping human-only features such as tabs and browser extensions.

In common agent tasks like screenshots and HTML extraction, Kitesurf uses much less CPU and memory than Chromium, so more sessions can run at once to handle AI-driven load.
