Trello.

Lots of half-baked clones but remarkably few quality foss implementations. WeKan is… a mess. Taiga is complex & the frontend is CoffeeScript (!!). FocalBoard looks about the best of them, but it’s still missing many features and they’ve explicitly rejected calls for OAuth and/ or SAML because they want as a paid feature.

I’ve also tried many products to replace Trello and finally settled with Taiga. It doesn’t look complex, and the UI is great too. The only missing bits I find are native mobile apps.
