Wekan

WeKan is a collaborative kanban board you install yourself. Boards give a visual read on where a project stands and keep attention on the few cards that matter, whether the project is a personal todo list, a holiday with friends or a company workflow.

Because it is free software running on your own computer or server, you never have to trust anyone else with the contents, and the project provides one-click installation across a number of platforms. The interface updates in real time, and the app has been translated into 234 languages, essentially all of them complete.

Running it in production carries real requirements worth reading first.

• Memory: one gigabyte free as a minimum, with four gigabytes total on a production server.
• Disk space: watch it and alert on it, because running out corrupts the MongoDB database.
• Updates: only the newest release is supported, and old versions carry security issues from outdated runtimes.
• Backups: daily at minimum, since there is no undo for a deleted list or card and some bugs stop a board loading.
• Scaling: large deployments split several frontend containers from one database server with many CPUs.

Containers are published on GitHub, Quay and Docker Hub, with a compose file in the repository, and the main branch runs on Meteor 3.5 with Node.js 24. Translations are accepted through Transifex rather than as pull requests. Commercial support is available, and the largest known deployment serves 30,000 users at one company.
