Cloudflare has launched Kitesurf, a stateless, highly scalable web browser that runs entirely on top of the company's Workers platform — and was designed from the ground up for AI agents rather than human users.

The announcement, made on August 6 during Cloudflare's 'Agents Week', positions Kitesurf as an 'agent-first' browser optimized for the workloads that matter to AI models: screenshots, HTML extraction and other common agentic tasks. According to Cloudflare, Kitesurf uses 3 to 7 times less CPU and memory than Chromium for those tasks, allowing developers to run more sessions and scale better for bursty, AI-driven workloads.

The browser is available for free while in beta. Existing clients keep working — developers simply add a 'browser=kitesurf' parameter to any Browser Run CDP or Quick Action endpoint to opt in, and a public playground lets users try it without writing code.

Kitesurf is one of several releases in a broader Cloudflare push to build what it calls an 'open agentic internet'. The company also unveiled WebMCP (giving any website a machine-readable interface for browser agents), a next-generation MCP protocol with a rewritten stateless core, the Agent Access Model for securing task-scoped agents, and Cloudflare OS, an open platform where agents and apps work together. Cloudflare argues that agents are a new kind of visitor — one that doesn't render CSS or click ads, but represents a paying human, so publishers and agents must learn to cooperate rather than collide.

With more than half of web requests now reportedly coming from machines rather than people, the launch highlights a broader industry shift: browsers, the tools humans used to reach the web, are being reinvented as infrastructure for the software that browses on our behalf.
