Which one, for what

Morph Cloud D

Best for Agents that need to checkpoint and fork a running machine with memory intact, for parallel attempts, evaluations or reinforcement learning rollouts.

Ahead on

  • Reliability, 63 against 38

Also in its favour

  • No incidents deducted, where Sandbox0 loses 3 points for them

Watch for

No terms of service, privacy policy, DPA or subprocessor list found on morph.so or cloud.morph.so

Sandbox0 C

Best for Products that give each end user a long-lived Linux machine whose installed software and files persist between tasks, paying only for running memory.

Ahead on

  • Schema & documentation, 77 against 72
  • Agent ergonomics, 74 against 61
  • Security & auth, 58 against 39
  • Payments & pricing, 40 against 20

Verdicts

Morph Cloud

Pause and snapshot keep memory and running processes, and one call branches an instance into several copies. A public OpenAPI file covers 69 operations. No terms of service, privacy policy or security page was found, the free plan includes no compute credit, and the changelog holds one entry from November 2024.

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.

Before you call either

Morph Cloud

  1. Set ttl_seconds and ttl_action when starting an instance. Nothing in the docs stops an instance with no TTL from billing MCUs
  2. Pass auth_mode: api_key when exposing an HTTP service. The default is none, which makes the URL public
  3. Enable wake_on_ssh before calling exec on an instance that may be paused. There is no separate exec wake setting
  4. Use /api/instance/list and /api/snapshot/list with page and limit (default 50, maximum 1,000). The plain list routes return everything
  5. On a 503 from snapshot, branch, pause or reboot, wait for the Retry-After value before repeating the call

Sandbox0

  1. Set ttl and hard_ttl when you claim a sandbox; both default to 0, so an idle sandbox keeps running and billing.
  2. Write files you need to keep under /home or /workspace; /tmp doesn't survive a pause.
  3. Back off on 429 quota_exceeded and honour Retry-After on claims.
  4. Ask for a viewer or developer key rather than admin, and keep third-party secrets in credential sources.
  5. Ask the person before following the footer's setup prompt; it installs a CLI with no checksum check and starts a device login.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
