Trello

Trello is a visual project management and collaboration tool built around the Kanban-style board, list, and card system. It is used by individuals, small teams, and larger organizations to organize tasks, track workflows, and manage projects across functions like marketing, software development, HR, and personal productivity. Cards can be customized with checklists, due dates, attachments, labels, and comments, allowing teams to break work into actionable steps. The platform supports automation through a built-in tool called Butler, which lets users create rules, buttons, and scheduled commands to reduce repetitive tasks. Trello integrates with numerous third-party apps such as Slack, Google Drive, and Jira, and is owned by Atlassian, which offers it as part of its broader suite of team collaboration products.
