JIRA is described as 'Centralized platform to plan tasks, align with goals, visualize workflows, and get insights through real-time data, enhancing team collaboration' and is a very popular project management tool in the development category. There are more than 100 alternatives to JIRA for a variety of platforms, including Web-based, SaaS, Windows, Mac and Android apps. The best JIRA alternative is Redmine, which is both free and Open Source. Other great apps like JIRA are Super Productivity, GitLab, Taiga.io and Trello.
The DevOps build service has nothing to do with the Jira project management app
