Vitals

Vitals is a Mac system monitor that shows apps instead of processes, so Google Chrome appears as one row with one memory figure instead of 96 helper processes you have to add up yourself. It keeps 30 days of history for every metric, alerts you when an app misbehaves, groups dev servers by project, and lives in the menu bar with every readout configurable. No subscription, one payment for life. Built by Atta Ur Rehman Shah.
