Lizmap is an open-source application that turns QGIS projects into interactive web map applications. It consists of a QGIS plugin, which prepares the project, and a web client, which displays it in a browser, so that map data prepared by GIS specialists can be shared with a wider audience. Lizmap can be installed and operated on the user's own infrastructure, or used through Lizmap Cloud, a hosted service that 3Liz operates for its customers.
Lizmap is published by 3Liz, a French limited company (SARL) registered in Montpellier, which also offers hosting and development services around QGIS. The software is licensed under the Mozilla Public License 2.0, with GPL and LGPL alternatives, so organisations can inspect the code and host it themselves. According to the Lizmap website, Lizmap Cloud services are hosted in France. For a European organisation, a French publisher combined with the option of self-hosting gives full control over where geographic data resides, although the hosting arrangement of any deployment should be confirmed in the contract.
