WeKan

WeKan is an open source Kanban board maintained in Finland and released under the MIT license. It delivers the familiar board, list, and card workflow of Trello in a package you can self-host on your own hardware, so no card, comment, or attachment ever leaves your infrastructure.

Cards support checklists, labels, due dates, comments, attachments, and per-board access controls, while swimlanes and WIP limits bring real Kanban discipline. WeKan installs through Docker, Snap, and most major platforms, runs on modest hardware, and has been translated by its community into dozens of languages.

Key features:

• True Trello-style boards with drag and drop cards, lists, and swimlanes
• WIP limits keep work in progress honest across every list
• Fine-grained access controls restrict boards and cards per user
• Self-hosted deployment via Docker, Snap, and standard Linux servers
• MIT licensed with fully auditable source code and no vendor lock-in
• Active community with frequent releases and dozens of translations

WeKan is led by maintainer Lauri Ojansivu with its trademark registered in Finland, and commercial support is available from the Finnish team. Because you host it yourself, GDPR compliance is structural: your task data lives wherever you decide, under European law, with zero third-party processors involved.

Ideal for privacy-conscious teams, public sector bodies, and self-hosters who want Trello's simplicity with complete data sovereignty at zero license cost.
