## Which one, for what

### 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 25
- Agent ergonomics, 87 against 70
- Security & auth, 58 against 47
- Payments & pricing, 55 against 20

Also in its favour:
- Free to start without a card

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

### Together Code Sandbox (D)

Good for: Teams already buying from Together, and former CodeSandbox SDK users, who want Docker-defined sandboxes with disk and memory snapshots from Python or TypeScript.

Watch for: The SDK and CLI work only for organisations Together has enabled, and the docs say to contact Together for access

## Verdicts

**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.

**Together Code Sandbox.** Two public OpenAPI documents, MIT clients for Python and TypeScript, cursor pagination and built-in retries make the surface easy for an agent to drive. Access is the limit. Together enables the SDK per organisation on request, publishes no rate limits or SLA, and neither status page names the sandbox service.

## Before you call either

### 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.

### Together Code Sandbox

1. Confirm the organisation is on Together's allowlist before installing. A valid `TOGETHER_API_KEY` alone is not enough
2. Build a snapshot first with `snapshots.create`. No default image exists, and every sandbox needs `snapshot_id` or `snapshot_alias`
3. Set `ttl` at creation or call `terminate()`. Nothing stops a sandbox otherwise, and closing the Python client leaves it running
4. Store the snapshot alias, not the sandbox ID. A terminated sandbox can't restart, and its state lives at `sandbox:<id>`
5. Exclude `snapshots.create` from retries with `should_retry`, and set `experimental.network_policy` before serving anything private on a port
