You lost me on the part where we create an in-browser screen recorder... and then proceed to package it natively.
If you are just lookin for a light screen recording utility, I suggest giving Spectacle a try.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Online screen recorders already exist too, I also don't think it really needs any server side logic either.
Spectacle only runs on KDE afaik, which is not the problem. But it also doesnt really compress much, I dont know if it uses the GPU too.
Agree spectacle + ffmpeg might be a good solution with postprocessing.
RecordScreen.io works for me when I want to do that. It's supposed to record locally (I've tried and have seen no data leaving my computer, but maybe should try taking it offline while recording, see if it breaks).
Thanks for an actually useful comment :D
It might be something like Photopea, that can also just be downloaded and ran locally.
If you want a screen recorder, try Kooha. Not exactly sure what you want, exactly.
Service as a software substitute
No, it is not a service if it runs locally in the browser.
And even less if you can load it from the system into the browser.
