Fieldkit: the free toolkit for Windows 10 and 11
Fieldkit is a free, open-source toolkit that lives in the Windows notification area. It brings a per-app volume mixer, a real system monitor, keep awake, a Dynamic Island in the taskbar, clipboard history, window layouts and more than 80 other small tools into one app. Every feature is a module, so you install only what you use. There is no account, no telemetry and no subscription.
Fieldkit is the Windows port of Vorssaint, the macOS menu bar utility.
What Fieldkit does
- Volume mixer: set the volume of each app separately.
- System monitor: CPU, memory, disk and network at a glance.
- Keep awake: stop the PC from sleeping while you work or present.
- Dynamic Island: a pill in the taskbar that expands into Controls, Music, Files, Notes, Calendar, Timer, Downloads and AI Agents pages.
- Clipboard history and window layouts: paste what you copied earlier and snap windows into place.
- Screenshot, quick notes, dark mode, empty Recycle Bin, eject all drives and dozens more one-click controls.
