slint – Native & resource-efficient GUIs in Rust

Slint is a state-of-the-art GUI toolkit written in Rust, specifically designed for lean, low-level user interfaces. With our upcoming Ezpire component for Slint, we are currently preparing the optimal foundation for deploying this powerful framework directly on PHYTEC hardware without lengthy configuration.

What is Slint?

slint is a declarative, open-source GUI toolkit that allows you to develop native user interfaces for embedded systems. The application logic can be flexibly structured in Rust, C++, JavaScript or Python to be written.

The UI itself is designed in an easy-to-understand markup language (Slint DSL) similar to HTML/CSS and translated directly into native machine code by the compiler. The result is an extremely fast, lightweight GUI stack that doesn't require a cumbersome runtime environment and runs smoothly even on systems with very limited memory.

Why Slint for embedded Linux?

  • Highest efficiency: The memory footprint (RAM) is minimal. No resource-intensive web engine is required in the background.

  • Modern developer experience: Benefit from features such as Live Preview directly in VS Code. Changes to the UI design are immediately visible on the screen without the need to recompile the code.

  • Hardware acceleration: Slint supports native rendering via OpenGL, framebuffer, or direct Linux KMS/DRM interfaces to optimally utilize the SoC's graphics hardware.

  • Safe and stable: Since the framework is primarily developed in Rust, it offers an extremely high level of memory security and system stability.

Our service: Slint integration

  • Integration Support: Our Field Application Engineers (FAEs) have already gained practical experience integrating Slint into Yocto environments on PHYTEC hardware. Contact us – we can actively support you with architecture and integration today!

  • New evaluation image (Coming Soon): We are currently preparing a dedicated Slint evaluation image specifically for our phyCORE-i.MX 8M Plus (phyBOARD-Pollux).

  • Pre-configured environment: Our goal is to provide you with a ready-to-use Yocto BSP in which Slint, the corresponding language bindings, and the appropriate hardware acceleration drivers (GPU/KMS) are already perfectly coordinated.

Stay tuned – the finished image and our detailed Yocto guides for a quick start will be available here soon!
