**Slint** is an open-source declarative GUI toolkit to build native user interfaces for any device.
Write your UI in `.slint`, a simple markup language, and connect it to business logic written in Rust, C++, JavaScript, or Python.
Slint scales from desktop apps to mobile apps on Android and iOS,
and down to embedded Linux and microcontrollers such as STM32, ESP32, and RP2040.

## Why Slint?

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](https://www.figma.com/community/plugin/1474418299182276871/figma-to-slint).
- **Stable APIs**: Slint follows a stable 1.x API. We evolve carefully without breaking your code.
