GeoServer is an open source server that can be used to provide INSPIRE compliant services such as discovery, view, and download services. It currently supports some but not all INSPIRE requirements. For example, it has robust support for mandatory coordinate reference systems and encoding formats, but its language and metadata support is only partial and some operations required by INSPIRE specifications are missing. The community is working to improve GeoServer's compliance with INSPIRE through additional plugins and extensions.
