E2B alternative
A Maritime sandbox runs E2B SDK code at $0.022 an hour for 2 vCPU and 4 GB against E2B's $0.1656, with no $150 platform fee, and Maritime adds Windows, Android and hosted agents. E2B gives a larger free credit.

What Maritime has that E2B does not.
E2B sells isolated Firecracker micro-VM sandboxes for AI agents to run code and tools, on Linux only. Maritime gives every agent its own computer: sandboxes, persistent agent boxes, Linux and Windows desktops, and Android phones, on one API.
Windows desktops
Maritime: $0.18 an hour while awake, licence included, with screenshot, click, type, files and human takeover. Requires Growth, Scale or Dedicated once the plan has been paid; not Starter or the free trial.
E2B: Linux only. E2B Desktop is an open-source Linux Xfce desktop.
Android phones
Maritime: $0.15 an hour while awake. AOSP Android 15 with tap, swipe, ui_tree, install_app and an adb tunnel.
E2B: No Android machine.
Persistent agent boxes
Maritime: $1 a month per 2 GB, awake or asleep. Keeps /data until you delete it, sleeps when idle and wakes in about a second on the next command, message, webhook or schedule.
E2B: Sessions last up to 1 hour on Hobby and 24 hours on Pro. Pause keeps filesystem and memory; the paused price is not stated.
Per-end-user spend caps
Maritime: End users are records keyed by your own id, with one agent each, per-user spend caps, short-lived eu_ tokens for their browser, and a usage report for rebilling.
E2B: A per-sandbox access token. No per-end-user records or caps stated.
Private network
Maritime: Reach a system inside a customer's office through a small connector on their side, no VPN, on every plan including the free trial.
E2B: VPC and BYOC on Enterprise only.
