Fluxer: sovereignty score and 8 European alternatives

Fluxer is a free, open-source chat app for friends, groups and communities. It offers text channels, voice, video and screen sharing and is available as a hosted service. You can also run your own instance; according to the project, messages, files and accounts are then stored on your own server. The source code is on GitHub under the AGPL-3.0-or-later licence.

Fluxer is operated by Fluxer Platform AB, a Swedish private limited company that, according to its privacy policy, is the GDPR controller; the Swedish authority IMY is the supervisory authority. For the hosted service, however, most stored data sits with Vultr in Piscataway, New Jersey (US); transactional email goes through Sweego in the EU, and voice traffic can be relayed through servers in locations including Frankfurt and Stockholm. If you need to decide where data is stored in Europe, self-hosting is the route to take. According to the project, it is funded by subscribers and donors, without venture capital.

Why digital sovereignty matters with Fluxer

Fluxer is headquartered in SE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Fluxer hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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