## 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:
- Schema & documentation, 87 against 74
- Agent ergonomics, 87 against 68
- Payments & pricing, 55 against 30

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

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

### Sprites (C)

Good for: Agents that need a long-lived machine with installed tools and files kept between sessions, and rollback by checkpoint.

Ahead on:
- Reliability, 55 against 45

Watch for: Four Sprites incidents on the status page in 90 days, including a partial outage of 7 hours 28 minutes on 23 September 2026 and failed creates outside Europe for 28 minutes on 8 October

## 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.

**Sprites.** A Sprite keeps a 100 GB ext4 disk between runs, bills compute only while active and can be checkpointed and restored through a published OpenAPI contract. The status page records four Sprites incidents in the last 90 days, one lasting over seven hours, and outbound network access is unrestricted until a policy is set.

## 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.

### Sprites

1. Create a token at sprites.dev/account after a browser signup, and send it as `Authorization: Bearer <token>` to `https://api.sprites.dev`
2. Follow the OpenAPI document, not the product page example. Create with `POST /v1/sprites` and a JSON `name`, and run commands with `POST /v1/sprites/{name}/exec` using `cmd` query parameters
3. Set a network policy with `POST /v1/sprites/{name}/policy/network` before running untrusted code. Egress is open until one is set
4. Processes started by exec stop on a cold wake. Define a Service for anything that must answer the request that wakes the Sprite
5. Create a checkpoint before a restore. Restoring replaces the filesystem, ends active sessions and keeps no copy of the replaced state
6. Sprite creation is limited to 10 a minute on pay-as-you-go. The Go SDK reads `Retry-After` and the error code `sprite_creation_rate_limited` on a 429
7. Delete Sprites you no longer need. An idle Sprite still bills cold storage for the bytes it holds
