Vikunja

Vikunja is a task manager that scales from a personal to-do list to light project management: tasks with due dates, labels and relations, shown as lists, kanban boards, tables or Gantt charts. Teams and namespaces make sharing clean.

It is a single binary plus a frontend, happy with SQLite for personal use. It aims at the Todoist/Trello space rather than heavyweight suites — you will not find time tracking empires or resource planning here, and that restraint keeps it pleasant.

A solid home for your tasks that no acquisition can sunset.
