EGroupware: sovereignty score and 8 European alternatives

EGroupware is an open-source online office suite for teams and organisations. It combines email, calendar, contacts, tasks, projects, timesheets, team chat, CRM, video conferencing, documents, helpdesk and kanban on one platform. The software supports open standards such as CalDAV, CardDAV, IMAP/SMTP, a REST API and OpenID Connect, and connects to LDAP and Active Directory. It comes as a Community Edition and an Enterprise Line, and you can switch between them without losing data. You can install it yourself or use it as EGroupware Cloud.

EGroupware GmbH is a German company that has developed software since 1996. EGroupware Cloud stores data in two separate data centres in Frankfurt, and the company cites German data protection law as the reason. The source code is published on GitHub. European organisations can therefore choose between self-hosting and a vendor-operated service in Germany. The company explicitly positions the product as a contribution to digital sovereignty.

Why digital sovereignty matters with EGroupware

EGroupware is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so EGroupware scores best on data residency.

EGroupware is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs EGroupware together with your other vendors and gives a total score, a heatmap and the main risk drivers.
