Slint is a declarative GUI toolkit for building native user interfaces for embedded devices, desktop, mobile, and web, with a custom .slint markup language. Business logic can be written in Rust, C++, JavaScript, or Python, with tooling including a live preview, LSP-based IDE integration, and a Figma import plugin.

Use cases

build a native desktop app UI in Rust
create a GUI for an embedded device like STM32 or RP2040
design cross-platform user interfaces with a declarative markup language
separate UI design from business logic for designer-developer collaboration
build a lightweight touch interface for an EV charger or HMI
compile a UI to WebAssembly for the browser
import Figma designs into a native UI toolkit

When to choose

you need a lightweight, low-resource GUI for embedded systems
you want a declarative UI language with Rust, C++, Python, or JavaScript bindings
you need cross-platform native look-and-feel from a single UI codebase
designers and developers must iterate on UI in parallel

When to avoid

you need a royalty-free license for commercial embedded products
you prefer building UIs directly in your programming language rather than a custom markup
you need deep ecosystem maturity comparable to Qt or Electron
your project requires complex web content embedding
