Slint
A declarative GUI toolkit for building native user interfaces across embedded, desktop, and mobile platforms using Rust, C++, JavaScript, or Python.
What is Slint?
Slint is an open-source declarative GUI toolkit that enables developers to build native user interfaces for applications running on embedded systems, desktops, and mobile devices. It uses a custom markup language (.slint) to define UIs, which are then compiled to efficient native code and integrated with business logic in languages like Rust, C++, JavaScript, or Python.
Developers and designers building cross-platform applications with native performance requirements, particularly those targeting embedded systems, desktops, or mobile platforms who want a declarative UI approach with multi-language support.
Slint offers a unique combination of a declarative UI language, true native performance across platforms, and support for multiple programming languages, all while being lightweight and scalable—making it ideal for resource-constrained environments like embedded systems without sacrificing developer or designer productivity.
