We have been using GitScrum since March 2016, and we are totally satisfied with it. The team is very responsive and really helps us to organize our workflows, improve our code quality and ensure that everything is in order. I would like to mention a few things that could be improved. It's not possible to search by tags (for instance "Jira"). This makes searching for issues difficult. Also, it's hard to filter issues by status or assignee. But these could be minor inconveniences. In general, it's working great! There aren't many open source tools we can use to manage our workflow. GitScrum has helped us organize our projects and help us control them. We're able to track all of our tasks easily and quickly.
