Notion vs Vikunja

Notion is a single space where you can think, write, and plan. Capture thoughts, manage projects, or even run an entire company.

Vikunja is an open-source task management application built around the idea that you should own your data. It supports List, Kanban, Gantt, and Table views for the same tasks, along with labels, due dates, reminders, task relations, and CalDAV sync, and can import existing tasks from Todoist, Trello, or Microsoft To-Do. It can be self-hosted for free via Docker or native binaries, or run on the official Vikunja Cloud hosted service for individuals, families, and organizations that prefer a managed option. The project is licensed under AGPLv3 with fully open source code.
