Quick Verdict
Choose Lunacy if you are a UI/UX designer needing a free, native desktop tool for creating mockups and prototypes, especially within a Sketch-based workflow. Choose Webflow if you are a web designer or developer who wants to visually build, launch, and host production-ready, responsive websites without writing code.
Lunacy and Webflow serve fundamentally different purposes within the design ecosystem. Lunacy is a desktop-based design and prototyping tool focused on UI/UX and vector graphics, offering full compatibility with Sketch files. Webflow is a cloud-based visual development platform that translates designs directly into clean HTML, CSS, and JavaScript, handling both design and web publishing. Their core difference lies in output: Lunacy produces design files and prototypes, while Webflow produces functional websites. Consequently, Lunacy targets designers in the early-to-mid design process, whereas Webflow targets designers and developers focused on the final production build.
