About Maritime

Maritime is a managed cloud that gives each AI agent its own computer. It is a Y Combinator company co-founded by Maria Gorskikh, and it runs every machine as a separate VM with its own disk that sleeps when idle, wakes quickly and bills per second. Developers use it to host agents, run untrusted code and drive apps that have no API.

There are six machine types: persistent Agent Boxes with a /data disk ($1 a month per 2 GB of memory), disposable sandboxes (from $0.011 an hour for 1 vCPU and 2 GB), invite-only swarms for batch jobs, Linux desktops ($0.12/hr), Windows Server 2022 desktops with the license included ($0.18/hr) and Android 15 phones without Google Play ($0.15/hr). Everything runs through one REST API, TypeScript and Python SDKs, a CLI and MCP. Plans cost $20, $100, $500 or $5,000 a month, each fee comes back as usage credit, and plans differ mainly by how many machines can be awake at once.

It fits teams that sell agents to many end users, since machines can be keyed to your own user IDs with per-user spend caps. E2B and Daytona focus on code sandboxes, Browserbase on headless browsers, and Scrapybara on desktops; Maritime bundles all of these on one bill. Windows needs Growth or higher, swarms are invite-only, and unused credit does not roll over.

On November 5, 2026 Maritime made its third Product Hunt launch, pitching cloud computers for any AI agent, and ranked #4 on that day's leaderboard. Buying tip: the 7-day trial caps usage at $20 and excludes Windows, so test Linux workloads first, then upgrade only if you need Windows desktops.

  3. 3Letting computer-use agents operate desktop apps such as QuickBooks Desktop
  4. 4Giving each customer of an agent product its own machine with a spend cap
  5. 5Testing mobile web flows on virtual Android phones

Best for

Startups building AI agents that need sandboxes, desktops or phones per user on a single API and bill.

Not ideal for

Teams that only need cheap code sandboxes or headless browsers at large scale (E2B, Daytona, Browserbase).

Integrations

  • REST API (OpenAPI)
  • TypeScript SDK
  • Python SDK
  • MCP
  • Maritime CLI
  • OpenClaw template

Our take

Maritime is worth a trial if your agents need more than a code sandbox, especially Windows or Android, and you want per-user cost tracking built in. Start on Starter for Linux work and move to Growth only when Windows is a must.
