Taiga

Taiga is an open-source agile tool that strips away unnecessary complexity and focuses on Scrum and Kanban workflows. The interface is straightforward and visual, with drag-and-drop boards, sprint planning, story pointing, and backlog management built in. You can host it yourself on your own servers or use their managed cloud version.

Taiga works well for software and product teams that practice agile but don't need enterprise-scale features or pricing. It's especially attractive to teams comfortable with self-hosting or those in industries where data sovereignty matters, since you own the code and can run it on your own infrastructure.
