Akira

you might find this a similar tool to other software like inkspace or other but its quite different. Its focus is on both user interface and vector graphics. Its completely written in Vala and build system is by Meson.

The main purpose of Akira is to offer a fast and intuitive tool to create Web and Mobile interfaces, more like Sketch, Figma, or Adobe XD, with a completely native experience for Linux.
