The OpenGeo Suite is a flexible set of open source components for spatial data sharing, mapping, and online editing. The OpenGeo Suite comes in three packages, with varying levels of support: Basic, Professional and Enterprise. The Suite includes PostGIS, GeoServer, GeoWebCache, OpenLayers and GeoExt. However, since it is modular and standard based (OGC) it can be combined with different software (such as UMN Mapserver, Mapnik, ArcServer and Oracle).
If someone does not want to pay for support, the components are all Open Source and freely available via the World Wide Web
