Some reasons to use Nextcloud include:

- It is free as in freedom and free as in beer: all official components of Nextcloud are free to use, and users only pay for support and update services.
- It has a long-term roadmap focused on extending "direct" user-to-user communication and cooperation features.
- It offers advanced security features such as brute-force IP whitelists, Content Security Policy (CSP), and Security Assertion Markup Language (SAML) support for secure, single sign-on (SSO) to web-based applications across different, independent servers.

To install Nextcloud, basic Linux administration skills and familiarity with the command line are needed. Nextcloud is a PHP application that requires a LAMP or similar software stack to work. It can be installed on almost any box permanently connected to the internet, from bare metal in a server farm to ordinary web-hosting accounts, or even home-based minicomputers like the Raspberry Pi. 

Nextcloud also offers many extensions, or "apps", that provide additional functions beyond basic file storage and sharing. Users can share single files or whole folders with others by giving them a link, with or without an associated password. Nextcloud's federation-related features allow users to share their content with other Nextcloud servers and access a "global address book".
