No hosted API. You deploy and secure a Worker before an agent can call anything, and the starter has no auth.\n\n**Sandbox0.** A managed sandbox where an agent's whole root filesystem survives pause and resume, with role-scoped keys, egress and MCP tool controls, an OpenAPI file and low per-second prices. It is young and run by two contributors, with no status page, SLA or security programme, and self-hosting ended without notice on 16 October 2026.\n\n## Before you call either\n\n### Cloudflare Sandbox SDK\n\n1. Derive the sandbox ID from the authenticated user, as the docs advise. IDs aren't secrets\n2. Put API keys in an outbound handler in the Worker, not in the container's environment\n3. Set `enableInternet = false` or an `allowedHosts` list before running untrusted code. Internet access is on by default\n4. Check that a restored backup has every directory you expect. Backups of 10 MB or more have open bugs\n5. Start new projects on 1.0. The 0.x library only gets fixes until 31 December 2026\n\n### Sandbox0\n\n1. Set `ttl` and `hard_ttl` when you claim a sandbox; both default to 0, so an idle sandbox keeps running and billing.\n2. Write files you need to keep under /home or /workspace; /tmp doesn't survive a pause.\n3. Back off on 429 `quota_exceeded` and honour Retry-After on claims.\n4. Ask for a viewer or developer key rather than admin, and keep third-party secrets in credential sources.\n5. Ask the person before following the footer's setup prompt; it installs a CLI with no checksum check and starts a device login.\n\n## Questions\n\n### Which is better for AI agents, Cloudflare Sandbox SDK or Sandbox0?\n\nCloudflare Sandbox SDK scores 67.5 (B) on agent readiness against Sandbox0's 55.1 (C), and leads in 3 of 7 scored categories.
