NextCloud

NextCloud is a self-hosted productivity platform that combines the convenience and ease of use of consumer-grade solutions like Dropbox and Google Drive with the security, privacy, and control that businesses need.

Features

Access to files wherever you are
With Nextcloud, you pick a server at home, in a data center, or at a provider, and your files will be there. With NextCloud running on that server, your data is protected and you can access it from your desktop or mobile devices. You can also access, sync, and share your data on that FTP drive at school, on Dropbox, or on a NAS you have at home.

Protect, control and monitor
With NextCloud, you can protect, control, and monitor data and communication across your company, ensure compliance with business and legal requirements, and keep your data on servers you own at all times. Nothing leaks, not even metadata.

Multi-platform productivity
You can enable productivity across any platform, whether in the office or on the road, to share, collaborate, and communicate across organizational boundaries. NextCloud provides transparent access to data on any storage.
Community
A thriving, transparent, entirely open-source community development model ensures constant improvements, free of lock-ins or paywalls, and enterprise support when you need it.
