Cloudflare open-sources Kitesurf, its browser for AI agents
Original title: Kitesurf is now open source
The Apache 2.0 engine runs on Workers, supports CDP and Puppeteer, and needs a Workers Paid plan to deploy.
Cloudflare released the source for Kitesurf, a stateless browser for AI agents that runs on Cloudflare Workers without a browser container. It parses HTML, applies CSS, executes page JavaScript, and renders screenshots, and it supports the Chrome DevTools Protocol so clients such as Puppeteer can connect. Developers can run it locally or deploy their own instance; a Workers Paid plan is required because pages use Dynamic Workers. Third-party Rust components keep their own licenses.
- The repository is on GitHub under the Apache 2.0 license.
- Engine, PageScript, and PageRenderer are the three main parts.
- Blitz, Stylo, Boa, Linebender libraries, and Krilla supply core functions.
- Local development starts with pnpm and wrangler on port 8787.
- Cloudflare says the engine is still under heavy development.
