by

Wekan is a web-based kanban board application that provides task distribution using intuitive graphics for better and modern team collaboration.

  • No monthly subscription payment fees
  • Can be hosted on your own server
  • Can be used in a private or local network
  • Continues releases and bug fixes from maintainers

For installation, Wekan uses Snap, which is simply a packaging software for cross-platform and dependency-free installation.

Wekan is administered under the MIT License and is currently supported by Wekan Team under its maintainer under the name of  ‘xet7’.
