Discover just some of the benefits of having a Kolab Subsciption

Many 'Open Source' companies provide both a Community and an Enterprise version of their software. Such 'Community Editions' often have significantly reduced functionality, sometimes to the point that they are largely useless if you want to use it in a production environment. The 'Enterprise' version may work, but is proprietary (not Open Source) and ends up locking you into the vendor. While these products are advertised as Open Source, what is being promised is not what you get.

Kolab Systems is different, and we have the 14+ year track record of Kolab to prove it. In 2016 we simplified our release model to make this as clear and accessible to everyone as possible. 

Kolab is developed in the open by the Kolab Community, and Kolab Systems is the founder and most active contributor in that community. Our release cycle looks like this:


You can install and run it on your own systems, and you can also subscribe to Kolab as a service. And if you want to run it professionally, a Kolab Subscription is the best way of doing so on any of the supported Platforms.

Of course we hope you will also get involved in and contribute to the Kolab Community.

No matter what you choose, some things will always remain true:

  • There is only one Kolab.
  • Kolab is fully Open Source, 100% guaranteed.
  • Our team is dedicated to deliver on our vision:
