Reminiscent of the now 18-year-old Cappuccino project https://www.cappuccino.dev/

Project that is still alive, amazingly.

The last release and blog post are from 2018, is it actually alive?

Yep! If you look at the GitHub repo, there is commits added in the last 5 days:

https://github.com/cappuccino/cappuccino/commits/main/

> Latest Version: 1.0.0 (September 4 2018)

There is a lot of work being done currently on the project as they prepare for v2.

cause there was Coffee Script, also, right?

The web version of Keynote with it was amazing.

I paid $20 for their interface builder and never got it.

Objective-J is something I entirely forgot existed.

I’d say this is closer to Blazor
