Tools / Lunacy

Design UI layouts with a free tool that runs on Windows, macOS, and Linux, opens Sketch files, imports from Figma, and works offline.
Lunacy is a free graphic design tool from Icons8, the company behind the icon and graphics library of the same name. It covers the core work of UI and web design: responsive layouts, vector editing, and auto layout. The app opens and edits .sketch files natively and can import projects directly from Figma, which makes it a practical option when your team works across different design tools.
It runs as a native app on Windows, macOS, and Linux, and there is also a browser version. Documents can be stored locally, so you can keep working without an internet connection, or you can use real-time collaboration and Lunacy Cloud when working with a team. That mix of offline desktop apps and shared cloud documents is what separates it from browser-only design tools.
Beyond the canvas, Lunacy ships with built-in Icons8 graphics libraries and UI kits, so icons, illustrations, and photos are available without leaving the app. AI-assisted features include a background remover, an image upscaler, an avatar generator, and a text generator, and the site also lists live web-page editing. The tool is free, with a paid subscription also offered; the page shows prices of $12/month and $9/month.
