A person must first deploy it on a Linux x86_64 host with KVM and Kubernetes.

Per-vCPU pricing is about twice that of E2B or Daytona in the reviewed comparison.\n\n## Before you call either\n\n### SPACE\n\n1. Ask your operator for the API base URL (before `/v1`, or `/api/v1` on shared hosts), the data-plane URL and a bearer token before planning any call\n2. Poll the returned operation until it succeeds and the sandbox is `running` before creating a command. A 202 response is not readiness\n3. Attach to the command's events URL with its session token to start the process, decode base64 output, and treat only `process_exited` as completion\n4. Send an `Idempotency-Key` on creates, lifecycle calls and commands, and retry only when `retryable` is true, after any `Retry-After`\n5. Save output as it arrives. Reconnecting with `Last-Event-ID` returns `resync_required`, not the missed output\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, SPACE or Runloop Devboxes?\n\nRunloop Devboxes scores 64.8 (B) on agent readiness against SPACE's 56.2 (C), and leads in 3 of 7 scored categories. SPACE leads on payments \u0026 pricing and transparency \u0026 trust.\n\n### Do SPACE and Runloop Devboxes need an API key?\n\nSPACE takes an API key or an OAuth sign-in. Runloop Devboxes needs an API key.\n\n### Can an agent call SPACE and Runloop Devboxes without installing anything?\n\nNo hosted endpoint is listed for SPACE. Runloop Devboxes has a hosted endpoint at https://api.runloop.ai.\n\n### Are SPACE and Runloop Devboxes open source?\n\nSPACE is open source (Apache-2.0). No open-source release is listed for Runloop Devboxes.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/perplexity-space-vs-runloop.json, and with the fewest tokens: https://www.anchorterminal.com/compare/perplexity-space-vs-runloop.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"perplexity-space\", \"b\": \"runloop\"}`.
