If you’re on Apple platforms you can try NetNewsWire. Comes with a Safari extension that you can use to easily add a feed and it syncs with iCloud and/or Feedly. Edit: grammar

I’ve heard about that, but it’s not available in the US yet.

That’s my problem, actually. I very much do not want music bundled with ad-free YouTube. I’d pay a reasonable price for an unbundled version, but the Premium family plan is more than the top-tier Netflix or Max subscription.

They already sent a legal warning to them but apparently didn’t realize that Invidious doesn’t use their API and never agreed to any terms of service.
