Mobilizon is a free and federated platform for organizing events and managing communities, developed by Framasoft as an ethical alternative to Facebook Events and Meetup. It allows you to create events, manage registrations, and federate groups, without advertising tracking or commercial exploitation of data.

Each instance relies on the ActivityPub protocol: it communicates with the rest of the Fediverse (Mastodon, other Mobilizon servers), so your events can be discovered and shared far beyond your own site. Users can have multiple profiles to separate their commitments.

Beyond occasional events, Mobilizon offers true groups with discussion spaces, shared resources, and publications, to sustain a collective over time. Geolocation, moderation, gauges, reminders, and calendar exports complete an experience designed for associations, collectives, and organizations concerned about their digital sovereignty.
