Radicale

Radicale is a simple open source server for calendars and contacts. It provides both calendar and contact server functionality while keeping setup and ongoing management to a minimum. Licensed under GPL-3.0, it is intended for people who need these server functions but want to avoid a substantial administrative burden. Its emphasis on extremely low overhead makes it suitable for users or administrators who prefer a straightforward system that requires little continuing attention. Radicale can replace Google Calendar when the main requirement is calendar server functionality, and it also handles contacts. One practical limitation is that Radicale is still server software, so it requires setup and ongoing management even though both are designed to be minimal. Its stated scope is focused on serving calendars and contacts, rather than on providing additional functions beyond those areas.
