About Costasiella

From it’s start as free open source yoga scheduling software Costasiella has been developed in close cooperation with it’s users. Due to this Costasiella contains many useful, time saving tools.

Above all, we’re definitely not done yet. Do you have a great idea or would like to start a project with us, please get in touch!

Open source

We believe that in order to be truly useful, software should be developed in the open. Everybody should be able to modify it to suit their specific needs.  It’s good to remember that no two organizations are run in the exact same way. Hence we aim to offer a free (as in free yoga class and in freedom) alternative to proprietary commercial solutions.
