Vikunja is a free, open-source task and project manager developed in Europe. It supports organizing work into tasks and projects with multiple views (lists, Kanban boards, Gantt charts, tables). The software can be self-hosted on the user’s own server (“Your data, your server”) or used via a hosted cloud service. It is licensed under AGPLv3 and fully open-source; the site notes it is “made and hosted in the EU” and offers optional paid hosting (Vikunja Cloud).
