Kopano Core provides the foundation for groupware messaging enabling clients such as Kopano WebApp, Kopano DeskApp, mobile and sync clients. With its modular architecture, Kopano Core enables the possibility for a variety of setup scenarios, scalable from a very low-powered system to a multi-datacenter setup providing messaging capabilities to tens of thousands of users.

In-depth documentation, such as administration and user manuals about our products can be found on our Documentation Portal. Additionally, a Knowledge Base is available for quick start guides, handy code snippets, and troubleshooting help.

The main development of Kopano Core takes place in a Bitbucket instance with development tickets organised in Jira. Please see CONTRIBUTING.md for steps on how to contribute patches.

Nightly builds of the master branch can be downloaded from https://download.kopano.io/. In addition to this, QAed builds of the release and stable branches are available to subscription holders from the Kopano Portal and a package repository.

Community Support is available through the Kopano Forum and through the #kopano channel on the Freenode IRC network. Additional support options are available for subscription holders.
