About Vikunja

Vikunja is a self-hostable to-do and project app that gives you list, kanban, gantt, table and calendar views over the same underlying tasks — so you're never locked into one way of looking at your work.

It's API-first and open source under AGPL-3.0, which makes it a natural fit for anyone who wants Todoist-style task management without per-user subscription pricing once it's self-hosted.

Key features

Five views, one task list — Switch between list, kanban, gantt, table and calendar views of the same tasks.
API-first design — A full REST API makes it straightforward to script, integrate or build on top of Vikunja.
Self-hostable — Run it with Docker on your own server and skip per-user pricing entirely.
Recurring tasks & reminders — Set up repeating tasks and reminders the same way you would in a commercial app.
