Best Agile & Issue Trackers (2026)

Plane is a modern, fast open-source project management platform positioned as an alternative to Jira, Linear, and ClickUp. Its AGPL-3.0 Community Edition self-hosts on Docker or Kubernetes at full parity with Plane Cloud, offering issue tracking, sprints/cycles, Kanban and Gantt views, project wikis (Pages), and an AI workspace. Founded in 2022 with teams in San Francisco and Hyderabad, it is the most-starred open-source PM project on GitHub.

Taiga is a free, open-source project management platform built for cross-functional agile teams working in Scrum or Kanban. Self-hostable on your own server (Docker), it offers backlogs, sprints, story points, customizable Kanban boards, issue tracking, a wiki, and time-tracking integrations, with a deliberately clean, usability-first interface. It is developed by Kaleidos Ventures SL in Madrid, Spain, and the backend is built on Django/Python.

ZenTao is an open-source project management system built around Scrum, Waterfall, and Kanban, with a strong emphasis on software R&D workflows. Developed by EasyCorp (Easysoft), it covers product/backlog management, sprints and tasks, bug tracking, test/QA management, document management, CI, and to-do management in one tool. The free Community edition is dual-licensed under ZPL and AGPL and self-hosts on a PHP stack; paid Pro and Biz editions add advanced features and support.
