Sure, but what is the advantage of using Freetube when you're running your own instance of Invidious? What extra functionality does it offer over what Invidious already offers? As far as I can see the advantages of hosting your own Invidious - or a similar application offering anonymous Youtube (etc.) access - outweigh those of using specific desktop/mobile applications like Freetube and Newpipe. I used to use Newpipe before I started hosting my own Invidious instance but more or less stopped using that app since then, not because there is something wrong with Newpipe but because there is no need for it any more.

I find freetube much nicer to use on a TV personally.
