Nextcloud Talk: sovereignty score and 8 European alternatives

Nextcloud Talk is the communication app of Nextcloud, offering chat, video and voice calls and webinars within the same platform as files, calendar and contacts. It supports calls with links for external participants, screen sharing, file sharing in chat, federation with other Nextcloud servers, and bridging to networks such as Slack, Teams, IRC and Matrix. Optional AI features provide transcription and summaries. Talk runs as an app on a Nextcloud server and is available on the web, Android, iOS and desktop. An optional High Performance Backend supports larger calls, and a TURN server is needed behind strict firewalls.

Nextcloud Talk is developed by Nextcloud GmbH, a German company with offices in Berlin and Stuttgart. The source code is licensed under the AGPL-3.0. Organisations can self-host Talk, including on-premises or in an air-gapped environment, or obtain it from a local hosting partner. This lets the organisation decide where conversation data is stored and who can access it. The encryption features the vendor describes are vendor claims and depend on the configuration.

Why digital sovereignty matters with Nextcloud Talk

Nextcloud Talk 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 Nextcloud Talk scores best on data residency.

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