Just saw a german Talk about this yesterday.

Versatiles provides a free and open to use Server under tiles.versatiles.org which is sponsored by People around the CCC.

Versatiles is also the First to offer a free to use vector card server, which is also amazing.

(For the German Readers: https://media.ccc.de/v/ds24-406-versatiles-freie-karten-fr-a...)

Yes, Versatiles is a nice truly open project! One of the long term plans for OpenFreeMap is to migrate to Shortbread + Versatiles styles.
