Cloudflare has launched Kitesurf, a cloud-hosted browser designed specifically for artificial intelligence agents rather than human users. The browser is built to help AI agents navigate websites, extract information, capture screenshots and complete web-based tasks while using less computing power and memory than conventional browsers such as Chromium.
Kitesurf runs on Cloudflare Workers and removes several features that human users typically need, including tabs, extensions and high-fidelity rendering. Instead, it focuses on requirements that matter to AI agents, such as context windows, token usage, performance, memory consumption and cost.
Unlike conventional browsers designed to render rich interfaces for people, Kitesurf is optimized for machine-driven tasks. It can load a webpage, read its content, or perform an action for an AI system.
Cloudflare said Kitesurf creates isolated browser sessions for individual AI tasks rather than maintaining long-running sessions. This makes it suited to short, bursty workloads where a browser can be created for a task and discarded after completion.
The company’s tests indicate that Kitesurf can use considerably fewer computing resources than Chromium for some common AI-agent workloads. It used 3.1 times less CPU while taking screenshots and 3.8 times less while extracting HTML. Memory use was 4.7 times lower for screenshots and seven times lower for HTML extraction. Chromium, however, completed the tests faster in overall wall-clock time.
Kitesurf works with Browser Run’s Quick Actions, Chrome DevTools Protocol and Model Context Protocol clients. Browser Run can handle tasks including capturing screenshots, generating PDFs, fetching rendered HTML and extracting structured information.
Developers can also use CDP to control browser sessions directly, while compatible AI coding agents can use MCP clients through CDP for tasks such as navigating webpages and taking screenshots.
Cloudflare said Kitesurf was developed in about 12 weeks. Its technology combines the Blitz rendering engine, Firefox’s Stylo CSS parser and the Boa JavaScript engine, with the remaining system running on Cloudflare Workers.

Kitesurf is not designed to replace Chromium for every browser workload. It currently lacks features such as video playback and WebGL and cannot handle some bot challenges that rely on conventional browser Transport Layer Security fingerprints.
It is also unsuitable for long-running workflows requiring users to remain authenticated and maintain persistent browser state. For those tasks, Cloudflare recommends its standard Browser Run option powered by Chromium.
Kitesurf is currently available in beta through Browser Run, subject to account limits. The launch reflects a broader shift in browser design as AI agents increasingly interact directly with the web, with Cloudflare focusing on lower computing costs, faster scaling, and simpler automation.
