Calypso is an advanced Python-based server solution that supports the CalDAV and CardDAV protocols. Originally a forked variant of the Radicale server, this software has evolved into its own unique entity, packed with useful features for data synchronization and sharing.
Features
Calypso's key feature lies in its support of both the CalDAV and CardDAV protocols. These protocols allow for easy synchronization of calendar events and contacts across numerous devices. The shared information can then be easily accessed using any device that supports these protocols, providing you with up-to-date details whenever needed.
Being developed in the Python programming language, Calypso allows for easy customization according to user needs. Its open-source nature invites developers to contribute to its development or tweak it to their liking. In addition, it's capable of running on almost any platform thanks to its reliance on universal Python interpreters.
