Any actual alternative software?

Hi, I have a My Cloud, and I’ve serched about changing the os, but everything is so outdated and not very clear, so I wanna know if there’s something actual, any so for the My Cloud tat works fine. It’s because I’m not happy with she system, and the android app, and windows app, the security, etc.

It will all depend on what version (first gen v4.x, or second gen v2.x) of the single bay/single drive My Cloud you are running:
