HumHub: sovereignty score and 8 European alternatives

HumHub is an open-source intranet and collaboration platform, described by the vendor as made in Germany. It combines a social network with spaces, a wiki, calendar and surveys, and can be extended with more than eighty modules, including single sign-on, LDAP and OnlyOffice. Typical uses are a company intranet, a knowledge base, a project hub or a community platform for customers and partners. You run HumHub yourself (on-premise) or take it as a SaaS service from HumHub.

HumHub GmbH & Co. KG is based in Munich, Germany. The core of the Community Edition is licensed under AGPL-3.0; the Professional and Enterprise Editions add a commercial licence and further modules. For the SaaS option, HumHub hosts on servers in Germany and the EU, and set-ups in other regions are available on request. The Enterprise Edition offers a dedicated, isolated hosting cluster. Organisations that self-host keep full control of the data, but must provide the technical skills for administration and updates themselves.

Why digital sovereignty matters with HumHub

HumHub 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 HumHub scores best on data residency.

HumHub 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 HumHub together with your other vendors and gives a total score, a heatmap and the main risk drivers.
