Reviewers see Lunacy as a fast, capable design tool that stands out on desktop, especially for Windows and Linux users. The most repeated praise is practical: reliable offline work, local file storage, smooth performance even on older machines, easy switching from Sketch or Figma, and a strong built-in library of vectors, UI kits, and stock assets. Users also call out useful workflow features like auto layout, Figma import, auto-coloring, and broad export options. Criticism is limited but specific: browser preview is awkward, settings feel sparse, and some want PSD or Adobe XD support.
