There's a couple of those for YouTube.

https://vid404.com/ is for videos with zero views. It generates search queries for finding them.

For videos with low views there's https://petittube.com/ (loads a random video with low view count) and http://astronaut.io/ (which has an "automatic stream" of videos).

KVN AUST on YT hunts zero-view videos, sometimes entertaining.
