Have you tried nothing at all? Had great success with this on a 150+ dev team. Much preferred to jira. Admittedly does require a different approach to work than a jira-centric team is going to be familiar with.

I 100%, sincerely agree that "nothing at all" is really a great option compared to Jira. I actually hired a whole person onto my project to make them responsible for ticket tracking, telling them they could use whatever they wanted so long as I never had to look at Jira again. They used Jira for a while because it's what other people were pressuring them to use, but ultimately they started using MS Planner. MS Planner! I mean, Planner is garbage too, but at least it's not Jira.

Where do you put the story points????
