Seems promising and I can't wait to see its memory usage. Already experimenting with it.

But I still believe that no one on the list, even Gluon, would be able to beat Sciter on memory usage. No one, by far.

In my real-world test, a web calculator app on Sciter used less memory even than gnome calculator on Linux, which is astonishing.

I saw multiple people (including the maintainer) talking about Gluon on Tauri Discord server, and it looks indeed promising.

About sciter, it looks like it grew since #251 :) It might become a bigger priority if that continues like that (Or if you or anyone want to propose a PR with working Windows/MacOS/Linux version I can merge it 👀 )

It's taking a lot of time to add things here now 😅 Fortunately, I automate many things to help things out
