Our verdict on CalendarIT
CalendarIT is a free, open-source calendar application for individuals and small teams that want to manage events on their own server. Its responsive web interface supports calendar views, event creation and editing, drag-and-drop movement, resizing, undo and redo, multiple calendars, visibility controls, categories, recurring events, and search by appointment title or location. Guest invitations and response tracking work through email, while browser and email notifications support everyday scheduling.
For synchronization, CalendarIT includes a built-in CalDAV server with two-way synchronization. It also supports iCalendar import and export, giving users practical ways to exchange calendar data across compatible tools. Recurring events can use RRULE exceptions, which is useful for schedules that change over time. These capabilities make CalendarIT a focused fit for people who want core calendar management and control over where their scheduling data is hosted.
The trade-off is a narrow platform and ecosystem focus. CalendarIT runs through the web and self-hosted deployments, with mobile support documented as a responsive web layout rather than native mobile apps. It does not provide integrations, scheduling links, or video support, and it has no AI features. Choose it for straightforward, self-managed scheduling with CalDAV; choose an alternative if native mobile applications, connected services, or built-in meeting coordination are central requirements.
