Linea21: sovereignty score and 8 European alternatives

Linea21 is a collaborative platform for steering and monitoring public policies and action programmes. It was originally designed for sustainable-development policies but can be used for any project management or reporting. Local authorities and other public bodies, as well as companies, record indicators, objectives and actions in it and report on progress. It is server software that you install yourself, and the project also offers an API. According to the developer, version 2.9 was announced in September 2026.

Linea21 is published by Intermezzo, an organisation based in Paris that advises local authorities on policy, participation and digital tools. The software is free and open; the Comptoir du Libre, the French catalogue of free software for the public sector, lists the GNU GPLv3 licence and Intermezzo as the service provider. Because you run it on your own infrastructure, policy and project data stay within your organisation. The publisher's website does not describe a hosted offering.

Why digital sovereignty matters with Linea21

Linea21 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 Linea21 scores best on data residency.

Linea21 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 Linea21 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
