Trello

Trello is the gold standard for visual, card-based project management. Its Kanban board interface (boards → lists → cards) is so intuitive that new users become productive within minutes, requiring virtually no training. The platform excels at simplicity: drag-and-drop task updates, customizable checklists, labels, and due dates keep workflows visible and straightforward without overwhelming users with unnecessary complexity. For indie hackers and solopreneurs, Trello's freemium model is unbeatable—the free plan includes unlimited cards, up to 10 boards, and integration with dozens of tools via Power-Ups (Slack, Google Drive, Calendar, etc.).\n\nWhile Trello lacks advanced features like Gantt charts, time tracking (native), and detailed reporting, its strength lies in doing one thing exceptionally well: task visibility and team alignment. Indie hackers often combine Trello with specialized tools for gaps (e.g., Toggl for time tracking). With 4.4/5 rating on G2 and a global user base in millions, Trello's simplicity and affordability make it ideal for bootstrapped startups managing 1–20 person teams.
