The challenge

Running a fleet of servers from a Mac is too often a patchwork.

Terminals opened one after another, scattered scripts, web panels that force a resident agent onto every machine: a process running non-stop, nibbling the very RAM you pay the server for.

A tool was missing that stays on the Mac's side: one that watches, deploys and protects servers without ever leaving anything running on them.

The interface

The whole fleet, at a glance.

The app · a server overview

The panel, from the menu bar.

Fleet status, pending updates, alerts and shortcuts: the essentials read without even opening the app, straight from the Mac's menu bar.

The crossing

A single principle, held end to end.

01 · Principle

Zero agent, zero resident

Everything goes through on-demand SSH commands. No process installed on the servers, nothing running when the app is closed.

02 · Watch

A watchdog that warns

A scheduled watchdog keeps an eye on the fleet and fires a push alert the moment a server stops responding.

03 · Trust

Ed25519 licenses, offline

License checks via Ed25519 signatures, verified locally. No license server to phone home, no telemetry.
