I use Windows App at work and honestly it's really good, a lot of QoL features, specially if you have to manage a lot of machines.

Servo is still going? Thought it was pretty much on life support after being abandoned by Mozilla.

Yes, it was revived by Igalia, and has good momentum. Check https://servo.org

Servo as a fully-featured web browser does indeed not seem to exist anymore but some of its components such as Webrender still do and are actively maintained.

servo was never a fully featured web browser and was never proposed to be iirc. It was proposed as experimental from the start. The most we got at the time was browser.html

Back in... 2018? there was a Servo binary you could download that had an address bar and could be used to browse the web. That actually started to get stripped down over time, the later binaries had less and less functionality, until now I don't even think there are any. Servo spearheaded a lot of projects, like bindings to macOS frameworks from Rust, that would have been used to create a more comprehensive browser, but then got torn down once the larger thing was canceled in favor of certain components, like webrender.

I don't know when exactly it was canceled - maybe around the time Firefox Quantum shipped.

Note that I never said it was ever not experimental. Just that it would have been more until it was canceled.

servoshell exists today. Their focus has definitely been in the rendering etc and not in developing browser UI, but that's understandable.

I've been using OvenMediaEngine for years which seems to be the same thing as this, but this looks pretty promising I'll give it a shot

For me there's honestly nothing better than: https://github.com/sylikc/jpegview

It's just so utterly fast (specially on opening times) I haven't been able to find anything even near it.
