    Has not been updated since 2014. Was fine at that time, now (2024, ten years after) it's kind of obsolete at least for serious work.

    LibreOffice Draw is a more fully-featured and customizable application than draw.io in my opinion. The main reason I think it is better, though, is because it is a native application, rather than something that forces you to use it online.

    Elements in quiver is forced to align with grid, not located by coordinates. Export format is different between quiver and draw.io also. Draw.io can export to svg, and pdf, while quiver can export to tikz or typst(wip)

    Does have a lot of graphics, but none of them let you change their content, only the title. For my use this makes it unusable. You cant even insert links or images. If only I could add text on these graphics, I would begin to use this tool.
