What Maritime has that Cloudflare does not.
Cloudflare sells serverless Linux containers next to Workers, with a Sandbox SDK on top for untrusted code. 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.
Cloudflare: Linux containers. Windows not stated, and no desktop.
Android phones
Maritime: $0.15 an hour while awake. AOSP Android 15 with tap, swipe, ui_tree, install_app and an adb tunnel.
Cloudflare: Not stated.
Persistent agent boxes
Maritime: $1 a month per 2 GB, awake or asleep. Keeps /data through sleep until you delete it and wakes in about a second on the next command, message, webhook or schedule.
Cloudflare: Disk does not survive a stop; only a snapshot or a mounted R2 bucket keeps files. Inactivity timeout up to 6 hours, with no guaranteed run time.
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.
Cloudflare: Not 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.
Cloudflare: Not stated.
