Trello pioneered the Kanban board approach to task management. Simple, intuitive, and now part of Atlassian. Power-Ups add functionality but the core is intentionally minimal.
Reviewer scorecard
“Local Markdown files mean I own my data forever. The plugin API is powerful — I built custom integrations for my dev workflow. Git sync works perfectly.”
“Simple and effective for small teams. Butler automations are surprisingly powerful. Best bang-for-buck PM tool.”
“The learning curve is real — you need to invest time building your system. But once set up, it is the most powerful personal knowledge tool available.”
“Not for complex projects, but for personal and small team task tracking it's hard to beat at this price.”
“My entire content pipeline runs through Obsidian. Research notes link to article drafts link to published pieces. The graph view shows connections I would have missed.”
“The visual simplicity is its superpower. Drag and drop cards, add covers, done. No learning curve.”
