Vikunja is an open source, self-hostable to-do app designed to help users stay organized and collaborate effectively. It allows you to organize all of your tasks in projects, create subprojects to organize everything hierarchically and keep related items grouped together. You can easily share a project with another user or a whole team, and assign tasks to people so everybody knows who's working on what. Vikunja offers multiple task views, including a classic list, Gantt chart, table, and Kanban board, allowing you to choose the layout that best suits your workflow. Tasks can be enhanced with features like reminders, recurring schedules, subtasks, labels, priorities, attachments, and relations to other tasks. The Quick Add Magic feature enables you to add tasks with due dates, labels, assignees, and more without additional editing. Vikunja also supports importing tasks from Todoist, Trello, or Microsoft To-Do, ensuring a smooth transition from other tools.
