Cloudflare Sandbox
Verified
Isolated code execution on Cloudflare, next to Workers.
Cloudflare Sandbox is the documented product for running untrusted or agent-generated code in isolated environments on Cloudflare, distinct from Durable Objects / Agents SDK. Use it when the factory already lives on Workers.

Editorial take
Separate from Cloudflare Agents on purpose: state vs isolation. This site’s jobs use Agents, not Sandbox, for YAML validation. If you execute model-written code, read this page, not the Agents quickstart.
Strengths
- First-party isolation on the same vendor as Workers.
- Documented as a sandbox, not only as a function runtime.
- Fits edge-shaped factories.
Limitations
- Cloudflare-only.
- Not a full desktop workspace.
- Limits and GA status move; read the current docs.
