Cloudflare open-sources Kitesurf, a Workers-based browser for AI agents

Cloudflare has released Kitesurf on GitHub under the Apache 2.0 license, letting developers inspect, modify, run locally, or deploy the browser on their own Cloudflare accounts. It runs on Workers, supports Chrome DevTools Protocol clients such as Puppeteer, and is still under heavy development as Cloudflare works on compatibility, reliability, and efficiency; deploying requires a Workers Paid plan.

Teams can evaluate or customize Kitesurf without relying on Browser Run’s managed APIs, but self-deployment requires a paid Workers plan. Its lighter resource use than Chromium is a stated goal, not a quantified result in this article, and compatibility remains an active limitation.
