General Bots Calendar vs Levenza Calendar

General Bots Calendar is a self-hosted team calendar for scheduling events, reminders and tasks. Users can request meetings, calls or reminders in natural language; invitations are sent automatically, and an availability endpoint can suggest open booking slots. The calendar has day, week, month and agenda views, mini-calendar navigation and keyboard shortcuts. It supports all-day and recurring events, personal reminders with lead time, and multiple calendars. Tasks with due dates appear alongside events, and completing a task updates its status on the calendar. REST endpoints cover event creation, reading, updating and deletion, plus free/busy checks. Calendar sync includes CalDAV servers. The calendar runs on customer-owned infrastructure and keeps data on the customer’s hardware; the full source is available under AGPLv3. Deployment is described as a self-contained Docker setup on a VM or bare metal. The Self-Hosted plan costs nothing, with unlimited users and operations and no per-user licensing fees.
