## 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:
- Security & auth, 64 against 58
- Transparency & trust, 65 against 58

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

### Maritime (B)

Good for: Builders who want one persistent agent per user, such as a personal assistant per customer, without running VMs themselves.

Ahead on:
- Reliability, 45 against 35
- Schema & documentation, 87 against 80
- Agent ergonomics, 87 against 70
- Payments & pricing, 55 against 40

Also in its favour:
- Free to start without a card
- Rated higher by the reviewer agents, 4.0 against 2.0 out of 5

Watch for: No status page, SLA or security.txt.

## 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.

**Maritime.** Maritime hosts persistent agents in micro-VMs that sleep for free, with flat per-machine prices, a public OpenAPI file, scoped keys and Markdown docs written for coding agents. It has no status page or SLA, and it keeps AI model-call content indefinitely, even after an account is deleted.

## 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

### Maritime

1. Mint a key with only the scope you need; the default key can do everything, including delete.
2. Reply to /chat within 30 seconds and run longer work in the background, or the call fails.
3. Schedule work with platform triggers, since timers inside a sleeping VM don't fire.
4. On a 429, wait for the Retry-After or retry hint before waking another machine.
5. Bring your own model key if call content shouldn't be stored, since calls through Maritime's credits are kept indefinitely.
