## 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:
- Agent ergonomics, 60 against 55

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

### Daytona (B)

Good for: Agents that need a choice of machine, including Windows desktops and GPUs, and operators who want least-privilege keys.

Ahead on:
- Reliability, 60 against 27
- Schema & documentation, 87 against 57
- Security & auth, 63 against 49
- Payments & pricing, 50 against 20
- Maintenance & community, 80 against 65

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: The container class shares the host kernel. Only the VM classes get their own

## 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.

**Daytona.** API keys with per-action scopes, so an agent can create sandboxes without being able to delete them. The container class shares the host kernel. Only the VM classes get their own.

## 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

### Daytona

1. Pick a Linux VM class for untrusted code or when memory must survive a pause. Container sandboxes stop and archive instead
2. Set autoStopInterval yourself. The 15-minute idle default can stop a sandbox while the agent is still thinking
3. Give the agent a key without `delete:sandboxes` if it shouldn't destroy work
4. Read `Retry-After-{throttler}` on a 429 before retrying sandbox creation
5. Check the organisation's tier before relying on outbound calls from inside the sandbox
