## 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:
- Maintenance & community, 65 against 43
- Transparency & trust, 56 against 40

Also in its favour:
- A hosted endpoint, with nothing to install

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

### DeltaBox Lite (D)

Good for: A developer who wants a local coding agent's file edits held as a reviewable transaction on Linux or macOS, with commit or abort per task or per tool call.

Ahead on:
- Reliability, 37 against 27
- Schema & documentation, 68 against 57
- Agent ergonomics, 67 against 60
- Payments & pricing, 60 against 20

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

Watch for: Version 0.1.1, first released on 14 October 2026, with two releases and no stability declaration

## 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.

**DeltaBox Lite.** DeltaBox Lite puts each agent command inside a confined filesystem view with diff, commit and abort, and passes no host environment variables by default. It is version 0.1.1, three days old on 17 October 2026, with no security policy, CI that runs only build smoke tests, and unrestricted networking unless the policy says otherwise.

## 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

### DeltaBox Lite

1. Skip step 5 of install-prompt.txt. Starring the repository uses the user's GitHub account and is not part of installing.
2. Pass `--commit` or `--abort` to `deltabox run` explicitly. The child's exit status is preserved after that decision.
3. Wrap redirection and pipes in `sh -c '...'`. An unquoted `>` is handled by the host shell and writes outside the sandbox.
4. Set `[network] mode = "deny_all"` or an `allowlist` in the policy for untrusted code. The default allows every destination.
5. Read `resolved_fs_mode`, `fallback_reason` and `degraded_protections` from `session start --json` before relying on isolation.
