What it does
Backlog is Nulab’s project and task management platform with issue tracking, Gantt charts, Kanban boards, milestones, Git/SVN, documents, and collaboration tools.
Organize work by project, assign tasks and due dates, and use Gantt and Kanban views to track delivery. Backlog combines project management, issue tracking, and collaboration; the vendor also lists a 10-user, one-project free tier and paid space-based plans. See the Backlog product page, features, and pricing.
The vendor says its Japanese plan lineup changes on January 1, 2027; confirm current terms before selection.
