Nextcloud is a suite of client-server software for creating and using file hosting services.

Nextcloud  provides functionality similar to Dropbox, Office 365 or Google Drive when used with integrated office suites Collabora Online or OnlyOffice. It can be hosted in the cloud or on-premises. It is scalable, from home office software based on the low cost Raspberry Pi, all the way through to full sized data centers that support millions of users. Translations in 60 languages exist for web interface and client applications.

The Nextcloud Conference is an annual event that brings together Nextcloud enthusiasts, contributors, developers, users, and industry experts from around the world. It is a unique opportunity to connect with like-minded individuals, learn about the latest developments in the Nextcloud ecosystem, collaborate, discuss, contribute, and help shape the future of Nextcloud Hub!
