You can use QGIS just as you always do to design and produce the maps you like. Once your map is ready, you simply need a web export plugin (like Qgis2threejs, qgis2web, or InteractiveMapForQGIS).

We're using Qgis2threejs in this example for its handy 3D capabilities (though it supports 2D as well). However, this specific plugin isn't mandatory, you may launch qgis2web or InteractiveMapForQGIS directly instead if you prefer!

This is where you export your work to the web. It works the same for qgis2web and similar plugins. Very important: Ensure that the main HTML filename is set to index.html (this is usually the default). If it is not named index.html, the hosted map won't open!

Log in to your Qgis2OnlineMap dashboard. You can drag and drop the resulting folder directly as-is, or the zipped version of it. Do not drop individual or separate files.

Once uploaded, you'll get a live URL instantly. Want to keep it private? Toggle the Password Protection switch in your map settings to restrict access to your clients or team.
