Cloudflare opens vibe-coding platform for non-coders with secure AI sandboxes

Cloudflare has open-sourced Cloudflare OS, its internal vibe-coding workspace that lets non-developers describe tasks in natural language and have AI agents generate apps. It uses fast, memory-efficient V8 isolates for per-task sandboxes, enforces strict permissions and disabled outbound networking, and runs client code in a browser sandbox. The platform supports multiple AI models, deterministic workflows to limit resource use, and admin controls for budgets. Cloudflare also published an Engineering Codex to uphold standards. Thousands of employees use it daily for docs, automation, and data visuals. Open sourcing is available on GitHub, but backend deployment requires a Workers Paid plan, and security researchers caution that sandboxing is not foolproof.
