Slint is a declarative GUI framework for building native user interfaces for Rust, C++ or JavaScript applications. Although it’s a multiplatform UI framework with important features such as live preview, responsive UI design, VS Code integration and a native user experience, we particularly want to highlight its usefulness for embedded systems. Teams developing embedded applications have traditionally faced a limited number of options for UI development, each with its own trade-offs. Slint offers the perfect balance between developer experience and performance, using an easy-to-use, HTML-like markup language and compiling directly to machine code. At run time, it also boasts a low-resources footprint, which is critical for embedded systems. In short, we like Slint because it brings proven practices from web and mobile development to the embedded ecosystem.
