Our criteria
For a tool to make this list: free tier with no time limit, supports at least 5 users without crippling, and the core feature (task tracking) is not gated.
1. ClickUp Free
The best free tier in the category. Tasks, docs, time tracking, dashboards — all functional. Storage is capped but that rarely bites for task management.
2. Trello Free
Personal Kanban for individuals or tiny teams. The free tier limits boards but is unlimited on cards. Simplicity is the selling point.
3. Notion (used as PM)
Free for personal use; very generous for small teams. Not strictly a PM tool but the database views make it serviceable.
4. Asana Free
Up to 10 users on the free tier with list, board, and calendar views. Loses timeline and reporting — fine for small teams that do not need either.
When the free tier stops being enough
Upgrade triggers we have actually seen: needing recurring tasks at scale, needing reporting for leadership, needing custom fields for complex workflows. Until then, free is fine.
