ownCloud
ownCloud is a self-hosted file sync and share platform that enables you to access, synchronise, and share your files from any device. Originally created by Frank Karlitschek in 2010 as a fork of KDE’s Personal File Sharing, ownCloud pioneered the self-hosted cloud storage category. It provides enterprise-grade file management with strong security features including encryption, versioning, and granular sharing permissions — all running on your own infrastructure.

- File versioning — Automatic version history lets you restore previous versions of any file
- Collaborative editing — Integrates with Collabora Online and OnlyOffice for real-time document collaboration
