Wekan

Wekan is a free, open-source Kanban board application that teams and individuals can self-host to manage tasks and workflows with complete control over their data. A privacy-respecting alternative to tools like Trello, it offers boards, lists, cards, swimlanes, and collaboration features under a permissive open-source license.

The platform provides classic Kanban functionality - boards with customizable lists and cards, drag-and-drop, labels, checklists, due dates, assignees, swimlanes, and card comments - plus features like time tracking and board templates. Being open-source and self-hostable via Docker, Snap, and other methods, Wekan appeals to privacy-conscious teams and organizations that want a Kanban tool entirely under their control.

Wekan is completely free and open source - there are no paid tiers or subscriptions; you self-host it for the cost of your own server, with optional commercial support and managed hosting available from third-party providers. Its combination of a familiar Kanban interface, data ownership, and zero license cost makes it popular with self-hosting enthusiasts, privacy-focused teams, and budget-conscious organizations. Aimed at teams wanting self-hosted Kanban, it competes with Trello, Taiga, OpenProject, Huly, and Planka.
