European alternative

[monty241]

Parts of the application are considered EE and not open source.

Cal.com is a US-based company and with geopolitical changes this can be a problem since the new administration can force cal.com to perform acts to get leverage over former US-allies.

For this reason, we are replacing Calendly. It seems cal.com is the only serious calendar software that supports Proton Calendar (CalDAV read-only).

Is there a known company that provides the EE features in Europe? And is not under US control nor dependent on the actions that Cal.com might be forced to take under US law?
