slint-ui/slint

Slint is an open-source declarative GUI toolkit for building native user interfaces for embedded systems, desktops, and mobile platforms.

Write your UI once in .slint, a simple markup language. Connect it to business logic written in Rust, C++, JavaScript, or Python.

The name Slint is derived from our design goals:

• Scalable: Slint should support responsive UI design, allow cross-platform usage across operating systems and processor architectures and support multiple programming languages.
• Lightweight: Slint should require minimal resources, in terms of memory and processing power, and yet deliver a smooth, smartphone-like user experience on any device.
• Intuitive: Designers and developers should feel productive while enjoying the GUI design and development process. The design creation tools should be intuitive to use for the designers. Similarly for the developers, the APIs should be consistent and easy to use, no matter which programming language they choose.
• Native: GUI built with Slint should match the end users' expectations of a native application irrespective of the platform - desktop, mobile, web or embedded system. The UI design should be compiled to machine code and provide flexibility that only a native application can offer: Access full operating system APIs, utilize all CPU and GPU cores, connect to any peripheral.

Beyond the design goals, here’s what makes Slint stand out:

• Independent UI Design: Use a declarative language to separate your UI from business logic. Designers can work in parallel with developers.
• Tooling: Iterate quickly with our Live Preview & editor integrations. Integrate from Figma with the Figma to Slint plugin.
• Stable APIs: Slint follows a stable 1.x API. We evolve carefully without breaking your code.
