Seems nice, but you need an external Player to watch the content, which can be goof for some people, but I like the webUI of TubeArchivist (even though it can be enhanced for sure)

I archive youtube videos that I like with TubeArchivist, I have a playlist for random videos i’d like to keep, and also subscribe to some of my favourite creator so I can keeptheir videos, even when I’m offline

This looks awesome ! Open-source software needs good design, and you got this right! I might need it in the future, so I’ll keep this on my toolbelt :)
