## 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.

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

### Vercel Sandbox (B)

Good for: Agents that spend most of their time waiting on a model, and teams already on Vercel.

Ahead on:
- Reliability, 70 against 63
- Schema & documentation, 77 against 72
- Security & auth, 80 against 39
- Payments & pricing, 40 against 20
- Maintenance & community, 80 against 58
- Transparency & trust, 75 against 25

Watch for: Tied to a Vercel team and project even when called from elsewhere, and access tokens reach the whole team

## 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.

**Vercel Sandbox.** Active CPU billing, so waiting on model responses costs only memory. Tied to a Vercel team and project even when called from elsewhere, and access tokens reach the whole team.

## 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

### Vercel Sandbox

1. Call `sandbox.stop()` when the task is done. Memory bills until the session ends
2. Use `Sandbox.getOrCreate` with a name so retries land in the same sandbox
3. Set `networkPolicy` to `deny-all` for untrusted code. The default is allow-all
4. Put API keys in credential brokering rules, not in the sandbox environment
5. Pass `persistent: false` for one-off runs so no snapshot is stored or billed
