Sorry, I'm just joining late.

Lizmap is a opensource solution that you can install on your own server.
So you need to care about hosting, upgrades etc.
The source code is on GitHub : https://github.com/3liz/lizmap-web-client/

Same for QGIS Cloud which is running QGIS Web Client, also available on
Github.
https://github.com/qgis/qwc2

Same for G3W-Suite : https://github.com/g3w-suite

But indeed, each of these products have also a paid hosting plan provided
by a private company if you don't want to care about hosting.
