## Which one, for what

### Morph Cloud (D)

Good 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)

Good 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
- Maintenance & community, 76 against 58
- Transparency & trust, 48 against 25

Also in its favour:
- Free to start without a card

Watch for: No status page, incident history or SLA found

## 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.
