About Lunacy

Best for designers wanting a free, full-featured desktop design tool.

Lunacy is a free design tool developed by Icons8 that works natively on Windows, macOS, and Linux. It supports Sketch file editing and offers a full-featured vector design environment for creating UI designs, wireframes, and prototypes.
