Radicale on a Mac
Lightweight CalDAV/CardDAV server · Calendars
Radicale is a small, simple Python CalDAV/CardDAV server — calendars, todos and contacts for any standard client (Apple Calendar, Thunderbird, DAVx⁵). Install with pipx (pipx install radicale) and run radicale — it listens on :5232 with a built-in web UI to create collections. Great as a drop-in replacement for Apple's old Calendar Server.
