Our verdict on Nextcloud Calendar
Nextcloud Calendar is an open-source calendar app for Nextcloud instances, aimed at individuals and teams that need shared scheduling with control over deployment. It supports multiple calendars, event management, recurring events, reminders, time zones, attendee invitations, and sharing with users, groups, and federated users. Web access and self-hosting are supported, while mobile workflows can synchronize through CalDAV on iOS and Android.
The calendar’s scheduling features extend beyond basic event entry. Teams can check free/busy availability, select meeting times, create appointment slots, and share public or private booking links. Published calendars can be embedded through an iframe, and iCalendar subscriptions and calendar export support exchange with external calendar systems. Booked appointments can also create Nextcloud Talk rooms, connecting scheduling with video meeting support. Integrations with Nextcloud Contacts and Tasks add context within the broader Nextcloud environment.
The app itself is available for self-hosted Nextcloud deployments, while the published paid tiers are Nextcloud Enterprise subscriptions that include Groupware and therefore Calendar. Standard costs €71.29 per user per year, Premium costs €104.99 per user per year, and Ultimate costs €204.75 per user per year; each plan starts at 100 users. That structure suits organizations seeking enterprise subscriptions alongside self-hosting, while smaller teams may prefer the open-source deployment. Choose Nextcloud Calendar for collaborative scheduling tied to Nextcloud and CalDAV; look elsewhere if time blocking or a standalone official mobile Calendar app is central to the requirement.
