[IMG: qt design tools]

[H4] Qt Design Studio
Qt Design Studio is an easy-to-use design tool that lets designers import designs from Sketch and Photoshop to Qt, customize and animate them, and turn them into QML code developers can use.

[H4] Figma to Qt
Designs that look perfect in Figma can fail on real devices. With Figma to Qt, you catch issues early, hand off real QML code instead of static files, and align design with development seamlessly. It’s the fastest way to bring Figma designs to life on actual products.

I use Figma and Qt Design Studio in parallel, and I have a streamlined workflow. I like Qt Design Studio because it is much more intuitive and interactive when creating and laying the components out. It enables me to develop the product rapidly.
