The folks behind Penpot also make a kanban management tool, kind of like Trello, called Taiga: <a href="http://taiga.io/" rel="nofollow">http://taiga.io/</a> It's also OSS (Django/Angular), self-hostable, and very pleasant to use.<p>I'm rooting for both of these, and now that they have some funding I hope they'll dedicate effort on polishing the rough edges (and do something about the gratuitous amount of white space that permeates all of their web presence, and maybe reconsider their color palette to be less muted and more saturated, heavier, and decisive). They seem to be actively working on Figma imports, auto layouts, multi-user edits and more at this moment so they're on the right track.<p>For both of them, <i>even</i> if the VCs pull the rug from underneath to race for an exit, it being OSS is good insurance. A fork would mean that we don't have to spend time learning yet another tool. The good will fostered by it being OSS is what encourages some of us to look into their offerings, and in this way what we see is something that seems like a sustainable model for OSS projects.
