For me, I've been using Figma to design wireframes and workflows.
I have tried https://meetalva.io/ but found it to be buggy and am also wary of a project small on community and exclusively powered by a company lacking a solid business model behind the project.
I haven't used @akiraux but plan to give it a shot when it reaches a stable release.
I've been curious about @glimpse , the fork of GIMP. Has anyone used either for wireframes and mockups?
Oh and I should have mentioned @inkscape which just released 1.0! Does anyone use Inkscape for wireframing?
