Marshal Stack is one screen for everything you have already shipped. Your apps in the App Store, the sites and APIs behind them, and the servers you run yourself ā all read by one rule: green is fine, amber needs a look, red is down. WHAT IT WATCHES ⢠App Store ā rating, review count, latest version, and the release state: in review, rejected, ready for sale. ⢠Sites and APIs ā checked every minute, with the latency next to the result. A notification arrives when an address stops answering twice in a row, and again when it recovers. ⢠Your own servers ā CPU, memory, disk, load and the heaviest processes, reported by a small agent you install with one line on a machine you already own. ⢠Alerts that say what to do, not only what broke ā memory over the threshold, a process running from /tmp, a port that was not open yesterday. YOUR KEYS, YOUR MACHINES Connect your own App Store Connect key, or none at all. The server agent dials out over HTTPS: it opens no port, reads no files, touches no databases, and uninstalls with one command. There is no registration form. Sign in with GitHub, or just open the app and look around on sample data bundled inside it ā no account, no keys, no network. ON THE WRIST The same three states on Apple Watch. A glance tells you whether anything needs you, and a tap opens the one thing that does. Free. No subscription, no in-app purchases, no ads, no third-party trackers.

Verdict
The clearest difference is update cadence: Ducat at every 3 days against Marshal Stack's every 3 weeks. Ducat also leads on iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
