Alternative to LVGL – Why teams move from
LVGL to Slint.

Advantages of Slint over LVGL

Declarative GUI

Stop writing and maintaining hundreds of lines of widget-creation calls. Describe the UI in the Slint language and let the compiler turn it into native code.

Live preview

Tweak colours, animations, geometry or text and verify the change instantly, without flashing the device.

GUI test automation

Catch regressions early: test the UI directly in VS Code or in your CI pipeline.

Your language, not only C

Keep the embedded logic in Rust or C++, and share the same UI with desktop tools written in JavaScript or Python.

Performant on small hardware

Slint picks the best rendering method for the hardware: GPU accelerated, DMA2D, framebuffer, or line-by-line when there is no room for a full framebuffer.
