Vikunja

Vikunja is an open‑source task manager that can be run on a personal server or accessed through a hosted cloud service. It stores tasks, projects, and rules under the user’s control, offering list, Kanban, Gantt, and table views that can be switched at any time. The software is licensed under the AGPL‑3.0, allowing anyone to read, modify, and redistribute the code without a subscription.

The system is designed for individuals who start with a simple to‑do list and can scale to team collaboration, supporting project sharing and task assignment without requiring a separate tool. Import utilities let users migrate existing tasks from services such as Todoist, Trello, or Microsoft To‑Do.

Installation options include Docker images, native binaries for various platforms, or a guided wizard for self‑hosting, while the cloud offering provides managed hosting with automatic updates and backups. The project is maintained by its founder and community, emphasizing privacy and user‑first development.
