Verdicts

Maritime

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.

Morph Cloud

Pause and snapshot keep memory and running processes, and one call branches an instance into several copies. A public OpenAPI file covers 69 operations. No terms of service, privacy policy or security page was found, the free plan includes no compute credit, and the changelog holds one entry from November 2024.

Before you call either

Maritime

  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.

Morph Cloud

  1. Set ttl_seconds and ttl_action when starting an instance. Nothing in the docs stops an instance with no TTL from billing MCUs
  2. Pass auth_mode: api_key when exposing an HTTP service. The default is none, which makes the URL public
  3. Enable wake_on_ssh before calling exec on an instance that may be paused. There is no separate exec wake setting
  4. Use /api/instance/list and /api/snapshot/list with page and limit (default 50, maximum 1,000). The plain list routes return everything
  5. On a 503 from snapshot, branch, pause or reboot, wait for the Retry-After value before repeating the call

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
