Office dwellers, what software/website or system do you use to keep track of tasks you need to do?

I use jira software for task management! It’s just me on the team, so it’s maybe a bit overkill, but I’ve found scrum / sprints to be massively helpful in prioritizing important work.

It sucks jira is in the cloud, but I’m yet to find an open source scrum system with the same features. Taiga.io comes close, but i don’t yet have a reason to switch; i’ve been using Jira for two years with no issues.
