Cloudflare released Kitesurf as open-source software under the Apache 2.0 license on Nov. 13, giving developers a Workers-based option for automated web tasks without a separate browser setup.
Hosted on Workers, Kitesurf parses page HTML, applies styles and runs scripts to produce screenshots. Developers can control it through Chrome DevTools Protocol-compatible tools such as Puppeteer, Cloudflare said.
Cloudflare reported that screenshot and HTML extraction work consumed less CPU and memory with Kitesurf than with Chromium. The company said the smaller memory footprint can allow more sessions to run concurrently.
The project targets AI agents that interact with websites, and Cloudflare says it accounts for token use, context limits, scalability, performance and cost. It puts less weight on human-facing options such as tabs, themes and extensions, or pixel-precise rendering.
Cloudflare first introduced Kitesurf in August, then added WebMCP support, APIs and compatibility updates in September. Cloudflare said Kitesurf is under heavy development, with work focused on compatibility, reliability and efficiency.
Developers can run the code locally or deploy it on Workers. A Workers deployment requires a paid plan because Kitesurf uses Dynamic Workers. Cloudflare directs developers to its changelog, web standards compatibility tests and benchmarks for updates.
