Thanks for your interest in our product, let me make it clear.
The Core of Lapentor is free to use: That’s mean you can create your Tours in our system, then download them to your PC and host it in your Hosting / Server, as much as you want, this is just like KRPano or other offline Software
But if you don’t have or don’t want to manage a Server to serve your Tours, you can use our Cloud Hosting service (which is $15/month). Every Tours published via Lapentor all have an URL like https://app.lapentor.com/sphere/project-name.
Whenever you make a change, you can just hit save and it will be applied immediatelly.
Actually you can find more information here, the paid service is only for Hosting.
