From the project
Independent Greaseweazle hardware derivative accompanied by GreaseGUI
An independent Greaseweazle hardware derivative accompanied by GreaseGUI, a friendly stand-alone Qt 6 application for reading, writing, and maintaining floppy disks. GreaseGUI communicates directly with compatible Greaseweazle firmware over USB.
GreaseGUI turns the common Greaseweazle workflows into a guided desktop experience while retaining direct access to the important drive, format, track-range, retry, and verification controls.
