Content material supply community service supplier Cloudflare has launched Kitesurf, a cloud-hosted browser designed particularly for synthetic intelligence (AI) brokers quite than human customers. In accordance with the corporate, Kitesurf is designed to assist AI brokers navigate web sites, extract info, take screenshots and full web-based duties whereas utilizing much less computing energy and reminiscence than standard browsers comparable to Chromium.
Kitesurf runs on Cloudflare Employees and strips away options that human customers sometimes require, comparable to tabs, extensions and high-fidelity rendering. As an alternative, it focuses on necessities particular to AI brokers, together with context home windows, token utilization, efficiency, reminiscence consumption and value.
The browser is on the market by Cloudflare’s Browser Run platform, which permits AI brokers to work together with web sites and carry out actions by browser automation. Browser Run itself helps duties comparable to navigating webpages, extracting rendered content material, producing PDFs and capturing screenshots.
What’s Cloudflare Kitesurf
Kitesurf is designed as a light-weight, cloud-based browser for AI brokers and automatic workflows.
Not like standard browsers, that are constructed to render wealthy interfaces for individuals, Kitesurf is optimised for machine-driven duties during which an AI system must load a webpage, learn its content material or carry out an motion.
It runs on Cloudflare’s serverless Employees infrastructure and is designed to create remoted browser classes for particular person AI duties quite than sustaining long-running classes.
This makes it notably suited to brief, bursty workloads the place a browser session could be created for a process and discarded as soon as the work is full.
How Kitesurf compares with Chromium
Cloudflare’s benchmarks counsel Kitesurf can use significantly fewer computing sources than Chromium for some frequent agentic workloads.
In accordance with the corporate’s exams, Kitesurf used 3.1 instances much less central processing unit (CPU) sources whereas taking screenshots and three.8 instances much less whereas extracting HTML.
Reminiscence consumption was additionally decrease. Kitesurf used 4.7 instances much less reminiscence for screenshots and 7 instances much less for HTML extraction.
Chromium, nonetheless, accomplished the exams quicker by way of general wall-clock time.
The comparability illustrates the trade-off behind Kitesurf. It’s not designed to interchange a completely featured browser in each scenario. As an alternative, Cloudflare is focusing on workloads the place decrease infrastructure necessities and the flexibility to scale giant numbers of short-term browser classes matter greater than most rendering efficiency.
Constructed for AI brokers
Kitesurf can work with Browser Run’s Fast Actions, Chrome DevTools Protocol (CDP) and Mannequin Context Protocol (MCP) purchasers.
Browser Run already permits builders to make use of Fast Actions for stateless duties comparable to capturing screenshots, producing PDFs, fetching rendered HTML and extracting structured info.
For extra complicated automation, builders can use CDP to manage browser classes instantly. Cloudflare additionally helps MCP purchasers by CDP, permitting appropriate AI coding brokers to navigate webpages, take screenshots and carry out different browser automation duties.
This implies builders can combine Kitesurf into present AI-agent workflows quite than constructing browser infrastructure from scratch.
Cloudflare stated Kitesurf was developed in about 12 weeks.
Its expertise combines a number of present parts, together with the Blitz rendering engine, Firefox’s Stylo Cascading Fashion Sheets parser and the Boa JavaScript engine, with the remainder of the system working on Cloudflare Employees.
What Kitesurf can be utilized for
Kitesurf is meant for AI brokers and automatic workloads the place a full Chromium browser will not be needed.
It may be used to render webpages, extract content material, generate PDFs and seize screenshots by Cloudflare’s browser instruments.
Cloudflare’s Browser Run Fast Actions already help duties comparable to changing webpages into Markdown, extracting structured JavaScript Object Notation information, scraping particular web page parts and retrieving hyperlinks.
Kitesurf is especially suited to short-lived duties as a result of every browser occasion can function independently and be discarded after the duty is accomplished.
The place Kitesurf falls brief
Kitesurf is just not supposed to interchange Chromium for each browser workload. It presently lacks help for options together with video playback and WebGL. It additionally can’t deal with some bot-challenge processes that rely upon standard browser Transport Layer Safety fingerprints.
The browser can also be not designed for long-running workflows the place customers want to stay authenticated and preserve persistent browser state. For such workloads, Cloudflare recommends utilizing the usual Browser Run choice powered by Chromium.
Browser Run helps full browser classes by instruments together with Puppeteer, Playwright and CDP, alongside less complicated stateless Fast Actions.
Kitesurf is presently in beta
Kitesurf is presently out there in beta by Browser Run, topic to account limits.
Cloudflare’s Browser Run platform itself is on the market on free and paid plans. The free tier presently consists of restricted every day browser utilization, whereas paid plans present larger utilization and concurrency limits.
The launch displays a broader shift in browser design as AI brokers develop into more and more able to interacting instantly with the online.
Conventional browsers had been designed round human behaviour: opening tabs, rendering wealthy interfaces and sustaining lengthy looking classes. AI brokers have totally different necessities.
