Newgrounds is great site to see classic old internet history in the form of videos & music. Recently, I've decided to take on the task of adding support for Newgrounds media to cobalt. Here is how I was able to read Newgrounds pages to find media.
cobalt, if you don't know, is an awesome social media content downloader. You all know those wonderful "youtube to mp3 no virus plz" sites. They are full of ads and tracking. That's where cobalt comes in. It supports a ton of different social media sites to download content.
Since cobalt is open source, anyone can grab the code and host their own instance. However, there is an official instance located at cobalt.tools. A few months ago, there was a small list floating around in the cobalt Discord of community instances. These were ones run by anyone and for fun. I decided to make a tracker for these instances.
