Cloudflare Launches Kitesurf, a Browser Engine Built for AI Agents

Cloudflare launched Kitesurf on August 7, 2026, a cloud-hosted browser engine designed for AI agents rather than humans. It runs in V8 isolates on Cloudflare Workers, skipping tabs, themes, and extensions. Cloudflare argues Chromium's memory and compute overhead makes per-agent instances prohibitively expensive at scale. Kitesurf is in free beta via Browser Run. Worth flagging: Cloudflare acknowledges prompt injection as a distinct threat but has not detailed mitigations.
