NethServer is an open-source server platform for small offices and medium-sized businesses. NethServer 8 installs and manages applications through a web interface using a container orchestrator, and can run on one machine or across several nodes, including in hybrid-cloud setups. Its modules include an identity module for single sign-on based on Keycloak, SOGo groupware, WebTop, a web server and WordPress. User domains and accounts are managed centrally. The earlier versions 6 and 7 have reached end of life.
NethServer is free software; several components, including ns8-core, are released under the GPL-3.0. The project's GitHub organisation lists Italy as its location, and the documentation carries a Nethesis copyright notice. Because you install the platform yourself, you decide where your data resides, for example on your own hardware or with a European hosting provider. In return you are responsible for installation, updates and security of the platform.
