So I've got a new domain and I want to do some fun stuff with it. Specifically, I'm looking for something that's fun to make as well as use.

I've got experience making webservers in p much every major language. My first instinct is to use NextJS just because it's fast and I've used it most recently, but then I also feel the allure of just rawdawging my own HTML/CSS+JS, like my forebears might've done. XML is kind of a pain to handbomb, though; all those closing tags, etc... Though I'm sure there are plugins for that.

Any suggestions? What was the last tool you used that really sparked your joy of creativity? Any really fun frameworks, stacks, editors, etc?
