The Castalia collective provides various collaborative services to its members, friends and like-minded people.

The services are free to use and provided under a “best effort” principle. If you or your organization relies on one of these, it is advised to let us know.

Looking for Castalia Solutions?


We have been around since 2003, supporting people and groups to communicate, organize and build a better world. Some of the communities that we have supported include juggling associations, music groups, country doctors, open source initiatives, and small, personal businesses.

We rely exclusively on openfree/libre open source software to build our services.


The services are maintained by Mistur and Boris Baldassari.
