Kitesurf runs on Cloudflare Workers and is available free in beta to developers through Browser Run.
Cloudflare launched Kitesurf, a cloud-hosted browser designed for AI agents, to help developers build software that navigates websites and completes tasks like filling out forms. The infrastructure provider positions Kitesurf as a tool for agents that need to use the web as humans do, without managing the visual elements that consumers see.
Cloudflare built Kitesurf on its serverless Workers platform and released it free in beta through Browser Run, a service for controlling headless browser instances. The browser uses a modular rendering engine from Blitz, the CSS parser Stylo from Firefox, and the Rust ECMAScript engine Boa JS, with the open source engine Obscura as inspiration.
For developers, the main benefit is lower resource use. Cloudflare says Kitesurf consumes less CPU and memory than Chromium for common agentic tasks such as screenshots and HTML extraction, which keeps costs down for production agents. The browser also faces a different threat model, including prompt injection attacks.
Kitesurf remains in beta and is available at no cost. Cloudflare says the browser passes roughly 215,000 web platform tests, adds more passing tests each week, and correctly renders pages like Wikipedia, Hacker News, the Cloudflare Blog, and much of the Cloudflare dashboard. Developers can watch those test totals grow as the beta matures.
What matters
- Cloudflare introduced Kitesurf, a cloud-hosted browser purpose-built for AI agents to navigate the web.
- Developers can use Kitesurf to automate form filling and site navigation without building a browser.
- Kitesurf passes around 215,000 web platform tests and adds more each week as it remains in beta.
