What free software can I use to create Bootstrap UIs / mockups quickly using GUI's drag and drops ?
So I avoid false-good-ideas such UXpin.com, from which the downloaded html code is very verbose and hard to reuse.
As far as I know, the only free Bootstrap mockup tools that I'm aware of are:
LayoutIt will not let you edit the generated code directly.
Bootply has both hand-coding (all users), and drag-and-drop (logged in users).
There is a review of tools here: http://tutsme-webdesign.info/best-bootstrap-visual-editor/
