🛠 Cloudflare open-sources Kitesurf — a Chromium-free engine for AI agents

The experimental engine runs on Cloudflare Workers without Chromium or browser containers: it parses HTML, applies CSS, executes JavaScript, and renders screenshots, PDFs, and HTML. It can be connected to Puppeteer, Chrome DevTools, and AI agents.

🌍 Browser automation for agents is getting cheaper: instead of heavy Chromium containers, the engine scales on-demand on serverless infrastructure, consuming less CPU and memory. Companies can deploy their own browser for agents via standard CDP.

👤 The code can be cloned and run with the pnpm run dev command, connecting Puppeteer, Chrome DevTools, or your own AI agent. Deployment requires a paid Workers plan, and the public URL should be secured with Cloudflare Access: the engine has no built-in authentication.
