People that stacked Inkscape
A powerful, free, cross-platform and open-source vector graphics editor. I use it to design logos, icons, and any other graphics that I need. The recent Inkscape 1.0 update brought a lot of awesome new features as well, particularly for Mac users.
In a world where illustrator costs way too much, Inkscape is one of the better alternatives for making quick designs and vector images to enhance the work I do. It's open source and constantly being tweaked so that's always a plus
