## Which one, for what

### Blaxel Sandboxes (C)

Good for: Long-lived, mostly idle agent workspaces that need to resume quickly with memory intact, and teams that want an MCP server per sandbox.

Ahead on:
- Schema & documentation, 80 against 72
- Agent ergonomics, 70 against 61
- Security & auth, 64 against 39
- Payments & pricing, 40 against 20
- Maintenance & community, 85 against 58
- Transparency & trust, 65 against 25

Watch for: 25 status-page incidents from 9 July to 1 October 2026, three of them sandbox outages over an hour

### 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 35

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

## Verdicts

**Blaxel Sandboxes.** No compute charge in standby, only $0.20 a GB-month of snapshot storage. 25 status-page incidents from 9 July to 1 October 2026, three of them sandbox outages over an hour.

**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

### Blaxel Sandboxes

1. Close WebSocket and terminal connections when done. An open connection keeps the sandbox active and billed
2. Set a TTL or idle expiry on throwaway sandboxes. The default is to keep them
3. Set `forbiddenDomains` or an allow list at creation, with `network.firewall` for tools that ignore proxy settings. Both can only be set when the sandbox is created
4. Retry only on WORKLOAD_UNAVAILABLE. The error reference says other codes won't succeed on retry
5. Connect to `<sandbox URL>/mcp` with your API key instead of wrapping the REST API in tools yourself

### 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
