What is Nextcloud?

Nextcloud Server keeps your files, contacts and calendars on a machine you choose and syncs them between your devices. People can share folders or single items with others and work on them together. Its main draw is the app store: Calendar, Contacts, Mail, Video Chat and hundreds of other add-ons turn a plain file host into a broader workplace platform. Security features named in the README include encryption, two-factor authentication and a HackerOne bounty program. The interface is available in 75 languages, and you can run it yourself, buy a device with it preinstalled or rent it from a hosting provider.

Good fit if

  • You want to replace Dropbox or Google Drive and also move contacts and calendars off a commercial cloud.
  • Your team needs file sharing plus chat, mail or video calls under one login on your own server.
  • You prefer a project with many hosting providers and appliances, so you are not tied to running it yourself.

Look elsewhere if

  • You only need fast, reliable sync of file libraries, with optional client-side encryption: Seafile.
  • You want peer-to-peer folder sync with no central server at all: Syncthing.
  • A lighter web file manager that stores data in S3 or OneDrive is enough: Cloudreve.

Before you adopt it

The server is released under AGPL-3.0, so a modified copy offered to users over a network must come with its source. The repository holds no paid parts, though Nextcloud GmbH provides a separate Nextcloud Enterprise offering for companies, the public sector and education. Contributors keep their copyright and sign off their commits, with no CLA required. Development is very busy, with 2633 commits in the last 90 days. A Docker image exists, but the repository has no compose file, and a git checkout needs submodules plus manually added apps, so production installs should use release archives.

Read from GitHub on 12 November 2026. How the score works

Nextcloud security

Security advisories are the vulnerabilities the maintainers disclosed on GitHub, with the versions that fix them; many advisories can mean careful disclosure as much as weak code. OpenSSF Scorecard checks how a project is developed and released: reviews, protected branches, pinned dependencies, signed releases. It does not audit the code itself.
