Nextcloud

Product overview

Nextcloud is a self-hosted file sync, sharing, and collaboration platform released entirely under the AGPL v3 open-source license. Founded in 2016 by Frank Karlitschek, who previously created ownCloud, Nextcloud GmbH is based in Stuttgart and employs about 150 people across 25 countries. The software is free to download and deploy on any infrastructure, with revenue generated through enterprise support subscriptions. Nextcloud Hub integrates file storage, video conferencing (Nextcloud Talk), calendar and contacts, collaborative document editing via Collabora or ONLYOFFICE, and an on-premises AI assistant. The platform supports WebDAV, LDAP, SAML, and federation between instances. Over 400,000 Nextcloud servers are deployed worldwide, and the main GitHub repository has accumulated more than 34,000 stars. Government adoption is a defining characteristic. The German federal government runs Nextcloud as its Bundescloud, France's DINUM deploys it across ministries, and the governments of Sweden and the Netherlands are users. Deutsche Telekom integrates Nextcloud as the backend for MagentaCLOUD. Other adopters include the European Data Protection Supervisor and Helmholtz Cloud supporting 14,500 researchers. Enterprise subscriptions start at approximately €15 to €22 per user per year. The community edition is fully unrestricted.
