I want a tool that runs outside the web browser if possible, but in-browser is OK if there's really no other way.
I've hunted around but so far have failed to find anything remotely like this. There are many channels that I love watching regularly but I do not want to use YouTube to know that there's a new video out on one of them.
Any ideas?
Google for “youtube rss url format” or “rss autodiscovery” for more.
Smartphone apps will work, too. NewPipe will do the job, as well as AntennaPod. Although the later will not download and play the videos.

these are RSS, then you use an application RSS reader (aggregator) like https://github.com/martinrotter/rssguard/releases
or even online http://www.feedly.com/ https://www.inoreader.com
