YesWiki: sovereignty score and 8 European alternatives

YesWiki is a free, easy-to-use tool for building online platforms for sharing and collaboration. It grew out of the wiki engine Wikini and is written in PHP. Besides wiki pages it offers a no-code form and database builder, role-based access rights, edit history, and displays as calendars, maps, directories, news feeds or photo albums. Extensions add, for example, learning-management features and QR codes. YesWiki is delivered as server software (PHP with MariaDB or MySQL) that you install yourself.

According to the project site, YesWiki is maintained by a French non-profit association (loi 1901) of general interest and developed by an open community; the project began near Montpellier in 2009. The software is released under the AGPL-3.0 and the source code is on GitHub. You can run YesWiki on your own servers, keeping your data under your control, or choose one of the partners that offer hosting; a test environment is also available.

Why digital sovereignty matters with YesWiki

YesWiki is headquartered in FR 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 YesWiki scores best on data residency.

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