A good kanban + project management application

Dream option: Taiga

Still good: https://wekan.github.io

Most basic: https://kanboard.org

for what it’s worth, I managed to install Kanboard relatively easy following this guide Installation Instructions — Kanboard documentation

if you want plugins follow these steps:

1:Rename&Check $(Kanboarddir)/config.default.php to config.php, and set parameter PLUGIN_INSTALLER to true
2:Check Permission $(kanboarddir)/plugins dir (need allow write www-user)
3:Need php-zip extension – install this by going to PHP PEAR Packages, searching zip and clicking install on Archive_zip
