Top alternatives to Keeper.sh
In its own words
The project's README opens: "Keeper.sh is a simple & open-source calendar syncing tool. It allows you to pull events from your Google Calendar, Outlook, iCloud, Fastmail, CalDAV server, or remotely hosted iCal and ICS links, and push them to one or many calendars so the time slots can align across them all. Google, Outlook, iCloud, Fastmail, and CalDAV are first-class integrations that can each be used as a source or as a destination, while iCal and ICS links are pull-only."
