Webwave (https://webwave.me/) generates multi-page websites based on an instruction and aesthetic choices.

Each block is finely editable.
The generated site is responsive (adapts to the size of the screen) and publication is possible (without setting the URL but which can be connected to a domain name).

With a free account, build a site with 1 GB of storage.

Test to be found here: https://csavl2.webwave.dev/ (raw generation, simple addition of a warning to indicate that it is a test site).
