Cloudflare open-sources Kitesurf for local runs and self-hosted Workers deployments

Top News

Running an agent browser does not have to mean running a browser container. Cloudflare has open-sourced Kitesurf, its browser engine for AI agents, so you can inspect the code, run it locally, or deploy an instance to your own Cloudflare account.

Here's what you can run:

• The engine renders web pages on Cloudflare Workers without a browser container.
• CDP support lets you use clients such as Puppeteer to control the engine.
• The GitHub source is available under Apache 2.0, so you can inspect the implementation before hosting it yourself.

One catch: Kitesurf is experimental, with standards support, rendering fidelity, and performance still under development. A self-hosted instance also needs an external authentication layer, such as Cloudflare Access.

Try it: Follow the build and setup instructions, then run pnpm run dev to build the engine and start Wrangler's development server.
