A ServerCat alternative for the whole fleet
ServerCat is a metrics dashboard for your phone. ServerShelf is the desktop cockpit, with a companion app for the phone.
ServerCat is an iOS, iPadOS and macOS app that reads CPU, GPU, memory, network, disk and Docker stats from Linux servers over SSH, with no agent. The dashboard is free; the SSH terminal, Docker management, background SSH and iCloud sync are premium at $5.99 per year or $18.99 once.
ServerShelf takes the same agentless SSH approach to a full desktop app on macOS, Windows and Linux: inventory with cloud import, scans, pending updates and patch runs, Docker control, TLS and uptime checks, hardware telemetry with alerts and AI log triage. The iOS and Android companion is included.

What is a good ServerCat alternative on the desktop?
ServerCat answers "is the box busy right now" from your pocket, and does it well. ServerShelf answers the questions that come after: what is installed, which packages wait for an update, is the certificate about to expire, what does the log say about the failed service, and who changed what. It keeps those answers in an encrypted inventory with projects and tags, imports servers from twelve cloud providers, and lets you act from the same window: run a snippet, restart a container, apply the update after a dry run. Hardware telemetry runs on a timer with temperature, disk and throttling alerts. The companion app on iOS and Android shows the fleet, receives push alerts and lets you snooze or acknowledge from the lock screen; destructive actions stay on the desktop on purpose.
ServerCat stays the better pick if all you want is a quick, cheap metrics view on the phone with an occasional terminal command. It targets Linux only; ServerShelf also scans macOS and Windows hosts over SSH.

Keep ServerCat or switch?
Keep ServerCat if a live metrics view on the iPhone is all you need and the servers are Linux. It is cheap, quick and does that one thing well.
Use ServerShelf if you administer the servers rather than glance at them: inventory, updates, containers, certificates, checks and log triage on the desktop, with the companion app for the glance and the push alert. The two do not conflict; ServerShelf's companion is read-mostly by design.
