The Qt licensing model is actually a bit less restrictive, since Qt is distributed under the LGPL, and Slint is full-fat GPLv3

Slint developer here.

Slint is under multiple licenses. The GPLv3 and also the Slint Royalty-free license.

For desktop applications, The Royalty free license is actually less restrictive than the LGPL since you can do static linking and don't need to share the modifications.

For embedded products, the LGPLv3 can often not be an option anyway, and we hope that users can find our pricing model better the one of Qt.

Can you share a ballpark estimate of what embedded runtime licenses cost? I really don't want to engage your marketing department to find out.

For non-commercial and personal projects, the runtime licenses are free.
