Eventkit-cloud is based on the HOT OSM Export Tool. It allows the user to select data from different sources to export into a variety of formats.
It is used to expose OSM and various OGC and ArcGIS services and allow users to generate datasets based on a map selection. These datasets will automatically include a map file (QGIS and ArcGIS), and can be made available for other users to download.
