We are the people who make Kolab, a highly scalable and secure collaboration platform that provides shared email, calendaring, notes, tasks, file cloud, tagging and much more. We ensure that you can use Kolab from the operating system and device of your choice, and that your privacy and security is in good hands as you do so. We could write pages covering all the features of Kolab, and we have: you can learn more about what Kolab has to offer here.

Kolab is used by Fortune 50 companies and small start-ups alike, by Germany's BSI, large municipal governments, ISPs and ASPs, school systems ... and people just like you who host their own private instance of Kolab for themselves, friends and family.

Kolab does all of this with 100% Free and open source software. It is developed in the open by a global community, with Kolab Systems serving as the project's steward. Visit the resources section of this page to find out how you can be a part of this!

Professional support is also available for Kolab from Kolab Systems, and you can even start using Kolab in a matter of moments by visiting Kolab Now which offers several hosting plans.
