Cloudflare has introduced Kitesurf, a lightweight browser created specifically for artificial intelligence agents. The tool can open pages, process content, and perform web tasks without loading every visual feature found in a browser designed for people.
Why does an agent need a browser?
Agents may need a browser to consult documentation, follow links, extract information, and complete processes on websites.
Traditional browsers include tabs, extensions, animations, and other features designed for people. An agent usually needs the page content, its links, and the controls required to complete a task.
Fewer features designed for people
Cloudflare created Kitesurf to focus on page processing and reduce some of the overhead of a traditional browser.
The company says it uses less memory and processing power than Chromium for some common agent tasks, such as extracting HTML content or producing screenshots. This advantage may vary depending on the page and task.
Kitesurf can process HTML, CSS, and JavaScript. However, it is not designed to reproduce every page with the same visual precision as Chromium. Some styles or animations may look different.
Compatibility with existing tools
Kitesurf uses interfaces compatible with the Chrome DevTools Protocol. This allows developers to use it with automation tools such as Puppeteer and Playwright without building an entirely new integration.
The browser operates within Browser Run, Cloudflare’s service for controlling browsers through code.
Separate and controlled sessions
Each session starts in a separate environment and maintains its own cookies. Different components can access only the resources required for their tasks, while external connections pass through controls defined by Cloudflare.
These measures reduce some risks, but they do not guarantee absolute security or provide access to private content without authorization.
Some parts of the system can also be started or discarded according to demand. This makes it easier to run many agent sessions without keeping all resources active permanently.
Availability during the beta
Kitesurf is available free of charge during its beta period through Browser Run. The tool remains under development, so its compatibility, behavior, and access conditions may change.
Cloudflare has not confirmed that it will remain free after reaching a stable release. Kitesurf is also not intended to replace Chrome, Edge, Firefox, or Safari as a daily browser for people.
