Open source. Safe. Scalable.

At WECHANGE you will find all the tools you need for your collaboration in one place, free of charge and without restriction! As a cooperative, we are completely geared to your needs. Our wide range of functions is therefore constantly being optimised and new features are being added. We only use proven open source technologies that meet the highest data protection requirements and are hosted by ourselves – not by profit-oriented data giants.
