Nextcloud Files is the file sync, share and document-collaboration product of Nextcloud GmbH, an open-source (AGPL-3.0) self-hosted platform with real-time document editing, file locking, end-to-end encryption, file access control and desktop/mobile clients. This entry covers the Files/document side; the DB also holds a separate Nextcloud entry under Team Collaboration (same vendor, different product angle, not a discontinued or renamed product).
