Introducing Maritime Sandboxes

Why it works

  • Lead with the biggest update and explain its practical details before moving on to secondary changes.
  • Clarify what is changing and what is staying the same to help existing users understand the impact.
  • Pair each announcement with a relevant next step, then close with a direct invitation for feedback.

How it is built

  1. Opening update framing
  2. Sandbox feature details
  3. Existing product clarification
  4. Swarms and Windows updates
Email copy

Hi [First name], This week brings many exciting updates to Maritime. As requested by many of our customers, Maritime now has Sandboxes: multi-purpose Linux machines you can start with one call. You can choose ephemeral or persistent sandboxes. Both are billed per second while running, from $0.022 an hour for 2 vCPU and 4 GB, and a paused persistent sandbox only pays for its disk. That makes them about 7.5 times cheaper than E2B or Daytona, and among the cheapest sandboxes you can get anywhere. Start an ephemeral sandbox. Your existing persistent sandboxes are now called agent boxes, and nothing has changed there. They're still $1 a month in your plan, and you'll find everything you had before in the dashboard, now under agent boxes. For Swarms, a lot of you asked for a whole server to host them, where your agents can spin up as many VMs as they want, of any size and any kind, and share RAM and SSD between each other. If you're interested, book a call with me. See how Swarms work. Windows desktops are out of beta. Anyone can now spin up Windows computers directly through the API, on the $100 Growth plan or higher. Read the Windows docs. Billing has changed as well. Your subscription stays the same, and you can now spend its credits on sandboxes and add-ons, as well as on agents. We're committed to being the most customizable sandbox provider, so you can add a static or residential IP, a private network into your customers' office, warm pools and an AI spend limit per agent, and request absolutely anything else. See all add-ons. Also, try our light mode and let me know if you prefer it. Would love to keep the feedback coming. Thanks for building with us. Best, Ary Shrivastava Cofounder, Maritime If you'd rather not receive these, unsubscribe here.
