Seeing the reception of the newly-open-sourced desktop environment, releasing the open-source kernel is going to be a major priority. I'm personally very excited about that, and I'm happy to see that's how other people want to use Puter too.
Also, I ran your hosting example and ended up with a static site at https://quiet-morning-9156.puter.site/. How long will that site be there? I assume not forever?
That's right, logically centralized and physically distributed (on our cloud infrastructure). The open-source kernel will likely include a filesystem driver for local disk instead of cloud storage (which is more convenient for self-hosting) with the option to also use cloud storage provided by puter.com.
Storage limits for puter.com start at 500MB for new users, with the ability to gain 1GB of storage by referring users (you and the user referred each get +1GB).
Static sites will be available until you decide to remove them.
