The service is still in beta, sandboxes need the $20 Pro plan, lifetime is capped at 30 minutes, and no sandbox operation appears in the published OpenAPI document.\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### Deno Sandbox\n\n1. Set `DENO_DEPLOY_TOKEN` to an organisation token (prefix `ddo_`) from Settings in console.deno.com. The organisation must be on Pro or above\n2. Pass `allowNet` on every `Sandbox.create()`. The Security page says outbound access is unrestricted when it is omitted\n3. Pass credentials through `secrets` with a `hosts` list, not `env`, so code in the VM sees only a placeholder\n4. The default timeout ends the VM when the client disconnects. Pass a duration such as `\"10m\"` and reconnect with `Sandbox.connect({ id })`, up to 30 minutes\n5. Create volumes in `ord` and start the sandbox in `ord`. A volume mounts only in its own region\n6. `exposeHttp` URLs are public with no authentication. Treat the random subdomain as a secret\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, Deno Sandbox or Sandbox0?\n\nSandbox0 scores 55.1 (C) on agent readiness against Deno Sandbox's 50.3 (D), and leads in 4 of 7 scored categories. Deno Sandbox leads on reliability and transparency \u0026 trust.\n\n### Do Deno Sandbox and Sandbox0 need an API key?\n\nBoth need an API key.\n\n### Can an agent call Deno Sandbox and Sandbox0 without installing anything?\n\nNo hosted endpoint is listed for Deno Sandbox. Sandbox0 has a hosted endpoint at https://api.sandbox0.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deno-sandbox-vs-sandbox0.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deno-sandbox-vs-sandbox0.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deno-sandbox\", \"b\": \"sandbox0\"}`.
