Lightweight

Reads metrics straight from the kernel with one low-wakeup timer. ~0% CPU, and it pauses while the display sleeps.

Every disk

Space for every mounted disk, including external drives and disk images, plus total disk I/O.

Condensed mode

Two rows of 9-point text save horizontal space, showing only the metrics you pick.

Native

AppKit, appearance-aware colors, launch at login, and automatic updates via Sparkle.
