Cloudflare Kitesurf
Cloudflare Kitesurf is a serverless browser for AI agents, built to run on Workers with stateless, per-session isolation and optimized for token and context-window efficiency over pixel-perfect rendering. It supports Puppeteer and Playwright, uses 3.1× less CPU and 4.7× less memory than Chromium for screenshots, passes 215K+ Web Platform Tests, and is free in beta via Browser Rendering, though it lacks video playback, WebGL, and full persistent-auth support.
