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**Runloop Devboxes.** Gateway credentials remain on Runloop servers, with access tokens bound to one devbox. Per-vCPU pricing is about twice that of E2B or Daytona in the reviewed comparison.\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### Runloop Devboxes\n\n1. Set an idle policy (`idle_time_seconds` with `on_idle: suspend`) so a forgotten devbox stops billing compute\n2. Route outbound API calls through an agent gateway instead of putting keys in the devbox environment\n3. Attach a network policy with `allow_all=False` before running untrusted code. Egress is open by default\n4. Restart background services after every resume. Nothing in memory survives\n5. Expect a 1-hour keep-alive cap and 3 concurrent devboxes while on the trial\n\n## Questions\n\n### Which is better for AI agents, Deno Sandbox or Runloop Devboxes?\n\nRunloop Devboxes scores 64.8 (B) on agent readiness against Deno Sandbox's 50.3 (D), and leads in 5 of 7 scored categories. Deno Sandbox leads on transparency \u0026 trust.\n\n### Do Deno Sandbox and Runloop Devboxes need an API key?\n\nBoth need an API key.\n\n### Can an agent call Deno Sandbox and Runloop Devboxes without installing anything?\n\nNo hosted endpoint is listed for Deno Sandbox. Runloop Devboxes has a hosted endpoint at https://api.runloop.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deno-sandbox-vs-runloop.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deno-sandbox-vs-runloop.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deno-sandbox\", \"b\": \"runloop\"}`.
