OpenSlides: sovereignty score and 8 European alternatives

OpenSlides is software for managing assemblies and meetings, covering agendas, speaker lists, motions, elections and participant management. It is free software released under the MIT licence and is available either as a hosted software-as-a-service offering or for installation on the organisation's own infrastructure.

OpenSlides is developed and maintained by Intevation GmbH, an independent IT service provider based in Osnabrück, Germany. Because the licence is open source and self-hosting is supported, a European organisation can run the software on its own infrastructure and keep control of its data. The vendor does not state where its hosted service runs, so organisations choosing the hosted option should ask for the data location and a data processing agreement in writing. The privacy policy refers to the GDPR and to processing in the United States for a third-party integration.

Why digital sovereignty matters with OpenSlides

OpenSlides 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 OpenSlides scores best on data residency.

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