I liked it so much that I went to look at the author Patreon[1]. His main thing is creating medieval fantasy city generator[2], which looks even better.
This is awesome. The creator is Oleg Dolya[1], who created wonderful roguelike mobile game Pixel Dungeon[2][3], which I spent months on playing on my tube commute until I managed to finish it with all characters.
It's just wonderful how a single person (I assume) can get the balance of all details and difficulty so right to produce something so rich and enjoyable. Highly recommended.
That is really cool! The quality on these is amazing!
I would love to read more about how it was made!
Also, it's a shame it's not open source. It would be cool to be able to add features that are specific to your game (for example, replace the fantasy things that can appear in rooms with Lovecraft themed things).
He is also an author of the Procgen Mansion [0][1][2] - procedural generator of buildings with a floor plans, which includes stairs, doors and windows.
[1]: The demo on that site utilizes keyboard not fancy buttons as in Fantasy City Generator, I recommend to quickly read information about key bindings.
The dungeons look great. One of the reasons is that they contain a lot of symmetry, which makes them more artificial looking than a typical random maze. Wonder how the code generates that symmetry...
I don't know how this code base does it, but I've seen another random dungeon generator that did a first pass generating symmetrical features and a second pass adding asymmetries to get a symmetrical-but-not-too-symmetrical look.
Another one that’s nice is a generator from Donjon. Source code only partially available though. His site offers many different types of generators: https://donjon.bin.sh/d20/dungeon/
Note that the author also has a fantasy city generator:

And mansion generator:

If you're into that kind of stuff, there's a world map generator(by different author):

Also, kinda relevant - awesome talks about modern procedural generation techniques(with AI, Houdini, etc):

Mindblowing talks by Anastasia Opara (using cool math, deep learning, and a lot of creativity to create crazy cool stuff)

She is the author of the most impressive procedural generation project I've ever seen:

Also, I myself have made a little tutorial about procedurally generating a 3D landscape in Houdini:
