Ahh just noticed it's made by graemeg, one of FPC long time contributors.

Many years ago I explored his fpGUI:

https://fpgui.sourceforge.net/ fpGUI Toolkit is a cross-platform GUI toolkit using Free Pascal

Nice to see you are not only limited to Lazarus

Interesting project! It is the first time I am hearing of it. I understand that the LSP support is in progress. It would be great if an IDE similar to Delphi could be developed as well - but I know that is a HUGE ask.

As usual, another release post with no mention of what the damn thing is.

“A modern, self-hosting Object Pascal compiler built for the 2020s. Zero legacy, full ARC, and unified UTF-8.”
