Masterportal
                                                    The Masterportal is developed in JavaScript, CSS and HTML and is based on several other robust OpenSource libraries such as OpenLayers, VueJS, Bootstrap 5 or ChartJS. It is published under MIT License and is thus available to be used in any context.
The Masterportal was originally designed by the city of Hamburg based on the needs of a smart municipality and is now being further developed by a large developer community.
