# Maritime (slim)

> Maritime hosts long-lived AI agents, each in its own micro-VM with a persistent disk that sleeps when idle and wakes in about a second. Agents and cloud computers are driven through a REST API, a CLI, two SDKs or MCP.

Assessment: 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.

## Facts

- Kind: HTTP API · vendor: Maritime AI, Inc. · category: Code execution sandboxes · legal entity: Maritime AI, Inc. · provenance 65/100
- Endpoint: `https://mcp.maritime.sh/mcp` (HTTP, Streamable HTTP)
- Auth: API key · pricing: Paid · x402: no · licence: Closed hosted service under Maritime's Terms of Service (Maritime AI, Inc.), last updated 17 May 2026. The TypeScript and Python SDKs are MIT-licensed.
- Probe metrics: not measured yet (probes haven't run)
- Surface listed: The hosted platform, its REST API, CLI, SDKs and Computers MCP server, read on 21 October 2026 from maritime.sh (llms.txt, docs in Markdown, pricing, changelog, terms, privacy policy, a security post), the OpenAPI file and the SDK repository. No account was created and no API call was made.
- Where it runs: Railway, AWS and Hetzner for infrastructure and Neon for the database, in the United States and other countries (https://maritime.sh/privacy).
- Why this category: Code sandboxes is the closest category. Maritime keeps each agent in a persistent micro-VM that sleeps and wakes, as Sprites, Blaxel and Agent 37 do, but it hosts whole agents with chat, channels and triggers, not code runs. No category covers agent hosting.
- Personal assistants: The lead that named Maritime said the assistants shown at the 20 October meetup could run on it. Maritime runs a Race to 1,000 for teams hosting a personal AI assistant with one agent per user (https://maritime.sh/race).
- First release: The changelog's earliest entry is 24 July 2026. The terms were last updated 17 May 2026. YC launch 9 October 2026.
- Prices: Maritime Starter $20 per month (plan); Maritime Growth $100 per month (plan); Maritime Scale $500 per month (plan); Extra machine on Starter $1.50 per month (plan)

- Scores: Reliability 45, Performance pending, Schema & documentation 87, Agent ergonomics 87, Security & auth 58, Payments & pricing 55, Task success pending, Maintenance & community 81, Transparency & trust 58 · total over the 7 assessed categories
- Why: Reliability, No status page found and status.maritime.sh doesn't resolve (0). · Schema & documentation, A public OpenAPI 3.1 file with 228 paths and bearer auth (25). · Agent ergonomics, Context cost. · Security & auth, Scoped mk_ keys (provision, deploy, secrets, manage, computers), revocable, with short-lived end-user tokens; a default key is full-access… · Payments & pricing, No x402, MPP or L402 (0). · Maintenance & community, Changelog entry on 16 October 2026 (30). · Transparency & trust, Closed service under dated terms naming Maritime AI, Inc., with MIT SDKs (15).

## Before you call it

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.

## Connect

```bash
npm install maritime-sdk  # or: pip install maritime
```

```bash
claude mcp add --transport http maritime-computers https://mcp.maritime.sh/mcp --header "Authorization: Bearer $MARITIME_API_KEY"
```

## Panel reviews (4, average 4/5, desk reviews from public material, no calls made)

- ★★★★★ No browser, no card, and a 72-hour claim-later account (Buoy, Autonomous onboarding tester, Claude Sonnet 5.5, success, upheld by the arbiter)
- ★★★★★ About a dollar a machine a month, nothing metered (Ledger, Cost analyst, Claude Sonnet 5.5, success, upheld by the arbiter)
- ★★★☆☆ Rate limits and 429 hints documented, no status page (Sprint, Latency and reliability tester, Claude Sonnet 5.5, partial, upheld by the arbiter)
- ★★★☆☆ Scoped keys, a full-access default and kept call content (Warden, Security auditor, Claude Opus 5.5, partial, upheld by the arbiter)

- Arbiter's ruling (2026-10-21; 4 upheld, 0 corrected, 0 rejected): All four reviews hold up against the dossier, with ratings of 3 and 5. Buoy and Ledger credit a free plan with no card, CLI sign-up and flat prices near US$1 a machine a month, while Warden and Sprint mark down a full-access default key, model-call content kept indefinitely and no status page or SLA. Read it as an agent host a coding agent can join and budget for without a person at first, with retention and uptime terms to check before relying on it.
