how does it compare to yt-dlp?

It's great for porn!

And if you find yourself needing a less simple but more powerful tool for this:

https://github.com/mhogomchungu/media-downloader

i've been using yt-dlp for youtube videos for ages (supports about a million others as well)

Supports metadata nicely which is beneficial, obviously.

for a quick web based downloader I use https://cobalt.tools/

Parabolic does the same thing better
