caldav.at is a CalDAV Server / CardDAV Server service provided by xeomueller in Nürnberg, Germany. Its core purpose is to synchronize calendars, contacts, and tasks through open standards. It emphasizes letting users freely choose compatible clients rather than being locked into a closed office suite, making it suitable for individuals, small teams, or associations that want to keep data consistent across iOS, Android, Windows, Mac OS X, Linux, and other devices.
The product is built around the CalDAV and CardDAV standard protocols, covering calendar, address book, and task synchronization. easy.Cal supports small teams of up to 5 employees and includes support for mobile and desktop devices, calendars, contacts, daily backups, optional shared access, German documentation, TLS encryption, and 24x7 email support; task functionality requires an additional fee under this plan. Pro.Cal is aimed at teams of 6 or more, with the page listing capabilities such as tasks, notes, daily backups, shared access, TLS encryption, custom domains, white-labeling, and email support. The page does not provide information on an admin console, permission roles, audit logs, or granular sharing controls, so it is more of a basic synchronization service.
Pricing is very straightforward: easy.Cal costs €5/month for 5 users, with task functionality costing an additional €1/month; Pro.Cal costs €10/month for 10 users. The page does not mention a free plan, trial period, annual discounts, payment methods, or pricing for additional users beyond the listed limits. For support, it advertises 24x7 E-Mail Support and provides German documentation plus setup guides for multiple platforms, but there is no visible phone support, ticket SLA, or enterprise support tier.
The strengths are its use of open protocols, freedom of client choice, low pricing, coverage of common collaboration data such as calendars, contacts, and tasks, plus TLS encryption and daily backups. The drawbacks are limited product disclosure: compliance certifications, data centers, backup policies, permission model, APIs, and integration ecosystem are not described. The page also does not clearly state whether self-hosting is available, so it is better viewed as a lightweight hosted synchronization service rather than a full enterprise collaboration platform.
It is suitable for individuals, small companies, associations, or teams that do not want to use the full Google/Microsoft ecosystem but still need open-standard synchronization. If you need complex permissions, enterprise compliance, mobile device management, or local Chinese-language support, alternatives such as Nextcloud, Microsoft 365, Google Workspace, or Baïkal, Radicale, and DAViCal may be worth considering. The page does not make it possible to assess access from mainland China, and payment methods are also not disclosed; before purchasing, it is recommended to test network connectivity, latency, and the efficiency of cross-border email support.
