@tomchadwin Thanks for mentioning. We have now a slightly improved version published: https://plugins.qgis.org/plugins/QuickWebViewer/

Still a long way to go to make it that smooth and fine-grained as #qgis2web, but it's a start to build a solution for low tech requirements and heavy maps suitable for the cheapest servers on the market. It's thought to fill the gap between your plugin and #QGISServer

Have a look at first examples we published using the plugin: https://censo2021.quickwebviewer.org/ and https://urba-conakry.quickwebviewer.org/
