This repo isn’t showing that at all. Scroll to the bottom of the README and you’ll see the other project it was based on.

My problem with this specific type of vibe coded project is that it’s initially presented as something more novel or polished in order to get more upvotes, karma, likes, or pad a resume. Then you read it and discover they just pointed Claude at some other projects and told it to produce something similar, then posted it as their own work.
