I remember seeing posts online where if you just search whatever manga you’re looking for with “raw” attached to it you get results just like any other manga site.

You could also join a fansub discord and ask them, I’m sure they’d be happy to have more translators.

My vote is for Proxmox because you can run all those other options (and many more) INSIDE Proxmox.

I used Google Lens on the picture and it brought up a lot of sites like Shutterstock. If you’re better with icons than me you can probably do something with it.
