Trello

Trello is a visual project management tool based on Kanban boards, cards, and lists, making it one of the most intuitive ways to organize work. Launched in 2011 and acquired by Atlassian in 2017 for $425 million, Trello has grown to over 100 million registered users and is widely used by teams of all sizes. The core concept is simple: create boards for projects, lists for stages (To Do, In Progress, Done), and cards for individual tasks. Cards can hold checklists, attachments, due dates, comments, labels, and assignees. Power-Ups (Trello's integrations) connect it to Slack, Google Drive, GitHub, Jira, and hundreds of other tools. While Trello started purely as Kanban, it now supports multiple views including Timeline (Gantt), Table, Calendar, and Dashboard through Power-Ups or the higher-tier plans. Trello is particularly popular with small teams, marketing departments, and anyone who finds traditional project management tools like Jira overly complex. The free plan is generous with unlimited cards and 10 boards, while paid plans start at $5/user/month.
