## Which one, for what

### Deno Sandbox (D)

Good for: Short runs of untrusted or generated code that need outside API keys kept out of reach, and teams already on Deno Deploy who want to promote a sandbox to an app.

Ahead on:
- Security & auth, 61 against 39
- Transparency & trust, 58 against 25

Watch for: Beta since 3 February 2026. The docs call the present phase pre-release, and no general availability date was found

### 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 48
- Schema & documentation, 72 against 66
- Maintenance & community, 58 against 45

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

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

## Verdicts

**Deno Sandbox.** Secrets stay outside the microVM and are substituted only on outbound requests to approved hosts, and an allowlist limits egress. The service is still in beta, sandboxes need the $20 Pro plan, lifetime is capped at 30 minutes, and no sandbox operation appears in the published OpenAPI document.

**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

### Deno Sandbox

1. Set `DENO_DEPLOY_TOKEN` to an organisation token (prefix `ddo_`) from Settings in console.deno.com. The organisation must be on Pro or above
2. Pass `allowNet` on every `Sandbox.create()`. The Security page says outbound access is unrestricted when it is omitted
3. Pass credentials through `secrets` with a `hosts` list, not `env`, so code in the VM sees only a placeholder
4. The default timeout ends the VM when the client disconnects. Pass a duration such as `"10m"` and reconnect with `Sandbox.connect({ id })`, up to 30 minutes
5. Create volumes in `ord` and start the sandbox in `ord`. A volume mounts only in its own region
6. `exposeHttp` URLs are public with no authentication. Treat the random subdomain as a secret

### 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
