You have valgrind and many other tools instead of "Instruments".

The GNOME project itself [1] has a lot of projects which compete with what you linked. Sure, Apple has a few billion dollars to dump into development every year, so you have to adjust for scale.

None of them has the polish of a full working desktop stack like macOS.

Once upon a time, around 2000-2, I did some minor contributions to Gtkmm.

I know GNU/Linux since 1995, eventually one gets tired of being part of the 3% desktop usage.

I'm still young and naive :P
