slint: A declarative GUI toolkit for building native user interfaces for any device.
What problem it solves
Building user interfaces for desktop, mobile, web, and embedded applications requires coordinating interface design with application logic across programming languages and platforms. Slint separates declarative `.slint` interface definitions from business logic and compiles the interface to native code.
Key features
Declarative interface markup — Define interface elements, placement, hierarchy, property bindings, and state-driven data flow in the `.slint` markup language.
Source: README
Multiple application languages — Connect interface definitions to business logic written in Rust, C++, JavaScript, or Python.
Source: README, api
Native compilation and configurable rendering — Compile `.slint` files ahead of time to native code and select from OpenGL ES, Skia, or software rendering backends.
Source: README
Editor and design integration — Work with live previews, editor integrations, a dedicated viewer, an online editor, and a Figma-to-Slint plugin.
Source: README, editors, tools
Cross-platform application scope — Use the toolkit for desktop, mobile, web, embedded Linux, and microcontroller applications.

Quick start
Copied verbatim from the project's README.
export component HelloWorld inherits Window {
width: 400px;
height: 400px;
Text {
y: parent.width / 2;
x: parent.x + 200px;
text: "Hello, world";
color: blue;
}
}Who it may suit
This may suit developers working in Rust, C++, JavaScript, or Python who need interfaces across desktop, mobile, web, or embedded targets. It may also suit UI designers working alongside application developers.
Topics to discuss
Which language bindings or target platforms should receive more community examples and documentation?
How can the `.slint` design workflow better support collaboration between designers and developers?
Which editor, live-preview, or design-tool integration would most improve day-to-day development?
