Lunacy is a vector design tool from Icons8 for UI and web design, positioned as an alternative to Figma and Sketch. According to its documentation, it is free to use, including commercially. It opens, edits and saves Sketch files natively and can also open Figma files. Built-in tools include background removal, image upscaling and placeholder text generation, plus libraries of icons, photos and illustrations. Lunacy is a desktop application for Windows, macOS and Linux. Local files work offline, while cloud documents allow real-time collaboration with comments.
Cloud documents are stored by the vendor, and the documentation does not state a hosting region. For teams with strict security needs, a Private Cloud is available either on-premises, on a dedicated server in the company's own network, or on a virtual private server that Icons8 deploys and maintains in any region or jurisdiction the customer chooses. Lunacy itself is proprietary software. Organisations that keep documents local, or choose the Private Cloud, can decide where their design data resides.
