The product launched on 29 September 2026. No status page, OpenAPI file, SDK library or published rate limits were found, and the starter credit needs a card.\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### Agent 37 Cloud\n\n1. Send the key as `Authorization: Bearer` to api.agent37.com and as `X-Agent37-Key` to the instance URL. The Bearer form on instance URLs is deprecated\n2. Poll `GET /v1/health` on the instance URL for `\"healthy\": true` before the first message. `status: running` only means the machine is up\n3. Check whether `error` is a string before reading `error.code`. Transport errors are flat strings, and a failed turn returns 200 with `status: \"failed\"`\n4. Don't blindly retry an exec that timed out after 13 minutes. The command keeps running, so a retry starts a second copy\n5. Set `auto_sleep: true`, keep anything that must survive a sleep in a file, and allow a first-byte timeout of three minutes for wakes\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, Agent 37 Cloud or Runloop Devboxes?\n\nRunloop Devboxes scores 64.8 (B) on agent readiness against Agent 37 Cloud's 46.1 (D), and leads in 6 of 7 scored categories. Agent 37 Cloud leads on transparency \u0026 trust.\n\n### Do Agent 37 Cloud and Runloop Devboxes need an API key?\n\nBoth need an API key.\n\n### Can an agent call Agent 37 Cloud and Runloop Devboxes without installing anything?\n\nYes. Agent 37 Cloud has a hosted endpoint at https://api.agent37.com/v1 and Runloop Devboxes at https://api.runloop.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agent37-vs-runloop.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agent37-vs-runloop.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agent37\", \"b\": \"runloop\"}`.
