Mobilizon: sovereignty score and 8 European alternatives

Mobilizon is open source software for creating, sharing and finding events and for managing groups. Organisers create and edit events, handle participation requests and publish through groups; people search by keyword, place or date and add events to their calendars. Mobilizon consists of independent, interconnected instances that federate through ActivityPub, so it can interact with fediverse software such as Mastodon. Organisations can install their own instance using the documentation or pay for professional hosting; public instances exist in several countries.

Framasoft, a French association, launched Mobilizon in 2020; in 2024 maintenance passed to Kaihuri, another French non-profit. It is free software under AGPL v3 or later. There is no single central operator: each instance operator decides where data is stored, so an organisation can host in an EU data centre under its own control or pick a public instance after checking its operator and country. Events shared across instances are copied to other servers. Self-hosting means handling updates and backups.

Why digital sovereignty matters with Mobilizon

Mobilizon 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 Mobilizon scores best on data residency.

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