How we found a bug in the hyper HTTP library

The Images service, built in Rust on Workers , runs on every machine in Cloudflare’s edge network. To handle client connections, we use hyper , an open-source HTTP library for Rust. Last year, we introduced the Images binding to enable custom, programmatic workflows for processing remote images in Workers. At the end of 2025, we rearchitected the binding to provide a more direc

Temporary Cloudflare Accounts for AI agents

Everyone's writing code with AI agents today. But the moment an agent needs to deploy something — and needs to sign up and create an account — it slams face-first into a wall built for humans: a browser-based OAuth flow, a dashboard to click through, an API token to copy-paste, a multi-factor authentication prompt to satisfy. For an interactive copilot sitting next to a develop

Build your own vulnerability harness

A few weeks ago, we published our initial findings from Project Glasswing , looking at what happens when you point frontier security models at an enterprise codebase. We also explored how our defensive structures adapt to protect our infrastructure and customers from threats posed by frontier AI . Since then, the AI ecosystem has continued to shift rapidly — developers who've b
