About Nextcloud

Nextcloud Server is a platform for keeping your files, contacts, calendars and other data on a server of your choosing. Content is synchronized across your devices, can be shared with other people for viewing or collaboration, and stays under your control rather than with a large cloud provider. It grew out of the ownCloud lineage.

Functionality can be expanded through hundreds of apps in its App Store, including Calendar, Contacts, Mail and Video Chat. Security measures include encryption mechanisms, a public bug bounty program and two-factor authentication. There are several ways to get a Nextcloud: sign up with a provider, install the server yourself on your own hardware or with a ready-to-use appliance, buy a device that comes with it preinstalled, or find a service provider to host it for you.

The server is written in PHP and JavaScript under the AGPL-3.0 license. Nextcloud GmbH also offers an Enterprise edition aimed at public sector, education and company users. It suits households, schools and organizations that want to replace commercial cloud storage and office suites with something they run themselves.
