Self-hostable video/audio calling and chat module within Nextcloud's open-source collaboration suite from Germany's Nextcloud GmbH.

Nextcloud Talk is the video and audio calling, chat, and screen-sharing module of Nextcloud, an open-source content-collaboration platform developed by Nextcloud GmbH, based in Stuttgart, Germany.

Because Talk ships as part of a self-hostable groupware suite, organizations can run it on their own servers or with EU-based hosting partners, keeping call metadata and recordings inside their own infrastructure rather than a vendor’s cloud.

Nextcloud GmbH sells enterprise subscriptions (support, security patches, scaling assistance) around the free, open-source core.
