Slint

A cross-platform UI toolkit for building native interfaces for embedded, desktop, mobile, and web from a single codebase. It solves the problem of fragmented UI development across platforms and languages. The toolkit targets developers and engineering teams in companies of all sizes, especially those in embedded systems, desktop applications, and cross-platform development.
