Is there any front end YouTube that can allow me to still comment?
Probably a dumb question, thanks for all the front end responses, I’ve been watching using them but want to engage. I really don’t want to keep using Google though!
Or should I just get used to not engaging or maybe bringing videos here and commenting if they’re that interesting.
The platform is owned by Google. By using YouTube in any way, watching, liking, subscribing, commenting, searching, clicking, all of it, you're "using Google".
So, the answer is that you cannot use YouTube and not use Google.
If Google is broken up, that might change, but I'm not sure if that will ever happen, what form that might take or if it would ever happen at all.
Judging from the last time I looked at their comment platform, it had the feeling that the only users of it were ones that were banned from Youtube because of the toxic shit they're wanting to post so I mean, I guess, but it's not the experience you're wanting, probably.
The closest that you can get is using something like Grayjay, where they have their own social media system, but your comments will only be interactable to other people using Grayjay.
Other responses have covered the “not without being logged into Google” part, so I’ll just add that if you don’t care about being logged into Google and the thing you want from a front end is Sponsor Block, then yes: YouTube in a browser with the Sponsor Block extension. On Android, the YouTube app w/ Revanced accomplishes the same thing.
