Project Management

Taiga

Open-source agile project management platform built around Scrum and Kanban, with backlogs, sprints, epics, user stories, issue tracking, and a wiki. The self-hosted stack is the same MPL-2.0 open-source code that powers Taiga's cloud product — self-hosting is free with no project, member, or storage caps and no feature gate; only the hosted cloud plans and an optional paid on-premise support/SLA contract sit on top of the identical software.
