## Which one, for what

### Agent 37 Cloud (D)

Good for: A product that gives each end user a long-lived agent machine that is idle most of the day and needs a harness preinstalled.

Ahead on:
- Security & auth, 49 against 39
- Maintenance & community, 65 against 58
- Transparency & trust, 56 against 25

Watch for: No status page was found. status.agent37.com returns 404, and the terms promise no uptime level

### 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 27
- Schema & documentation, 72 against 57

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

## Verdicts

**Agent 37 Cloud.** Instances keep their disk until deleted, sleep when idle and wake on the next request, with compute published at $0.80 a vCPU-month and stable error codes on both APIs. The product launched on 29 September 2026. No status page, OpenAPI file, SDK library or published rate limits were found, and the starter credit needs a card.

**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.

## Before you call either

### Agent 37 Cloud

1. Send the key as `Authorization: Bearer` to api.agent37.com and as `X-Agent37-Key` to the instance URL. The Bearer form on instance URLs is deprecated
2. Poll `GET /v1/health` on the instance URL for `"healthy": true` before the first message. `status: running` only means the machine is up
3. Check whether `error` is a string before reading `error.code`. Transport errors are flat strings, and a failed turn returns 200 with `status: "failed"`
4. Don't blindly retry an exec that timed out after 13 minutes. The command keeps running, so a retry starts a second copy
5. Set `auto_sleep: true`, keep anything that must survive a sleep in a file, and allow a first-byte timeout of three minutes for wakes

### 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
