## CreateOS Sandbox (NodeOps)

- `compute/createos` | qualifies-with-caveat | evidence documented | binding request-rate | category container and VM sandbox
- identity a placeholder: card and phone unknown | verified 2026-11-04T05:24:08.726Z (live) | stale on 2026-12-05
- url https://createos.sh/products/sandbox
- free tier: 500 free credits to start; a sandbox auto-pauses after 5 minutes idle with memory and disk preserved and compute billing stopped | unit: mixed | metered on: wall-clock | read on: 2026-10-22 | source: [1]
- per-object cap: not stated | source: [1]
- retention: not stated | source: [1] | note: not stated
- egress: egress is unmetered at $0 at any volume; outbound traffic is firewalled to an allowlist and there is no ingress by default | metered: no | free allowance: unlimited | price per TB: $0 | source: [1]
- identity: email
- interface: rest, cli
- limits:
  - request-rate (binding): 500 free credits at signup [1]
  - retention-clamped: auto-pause after 5 minutes idle; memory and disk are snapshotted rather than lost [1]
- limits note: not stated
- interface detail: REST API, CLI, a TypeScript SDK and MCP; no Python SDK
- tooling: the same as limits note
- composes with: the same as limits note
- reliability: no reliability event recorded
- evidence note: the sandbox page was read on 2026-10-22. The 500-credit grant is one-time; the 5-minute auto-pause is the wall-clock axis and it preserves state, which is the unusual half
- extras:
  - keep_rate: 1.0
  - keep_rate_basis: first-party: PAUSED sandboxes stop vCPU billing but KEEP billing RAM at $0.01159025/GB-h
  - billing_model: unclassified
  - session_cap.idle_reap_s: 300
  - session_cap.restart_required: no
  - session_cap.note: auto-pause at 5 minutes idle; the snapshot restores guest memory and device state, so the clock costs wall time but not work
  - persistent_storage.price_gib_month: not published on this page
  - persistent_storage.durability: Firecracker snapshot on disk
  - persistent_storage.survives_stop: yes
  - persistent_storage.survives_destroy: no
  - persistent_storage.max_retention: until deleted
  - free_tier_kind: one-time-credit
  - granularity.min_billed_s: 0
  - burst_x: 1.0
- evidence:
  - [1] 2026-10-02: 
  - [1] 2026-10-22: '500 free credits to start.' and 'Idle 5 min → paused, disk + memory preserved' with 'A paused sandbox is a Firecracker snapshot on disk: guest memory and device state are frozen, and compute billing stops', quoted
  - [1] 2026-11-04: SDK, CLI, MCP and REST API | capture: sha256:771920ef867e86ee0ae168d9e61c0e342467ca3822ac771b318eef5be94bd317 | quote: A TypeScript SDK, the CLI, MCP, or the REST API from any language, so an agent can provision its own compute through a tool call.
  - [1] 2026-11-04: egress is not charged | capture: sha256:771920ef867e86ee0ae168d9e61c0e342467ca3822ac771b318eef5be94bd317 | quote: Networking is unmetered, so egress is $0.
