Yeah, I'm not even sure what this is, or whether or not this is even intended to be a serious project. It just comes across to me as deeply unprofessional. I say this as someone who doesn't even like Vercel and has their own gripes with that bizarrely run company.
The docs say that none of the code has been reviewed or tested properly, so how serious is this for people to run in a production setup where many companies are going are not going to be super enthused that their production environment has been 'vibecoded' in a week? It just reads to me like a not-so-subtle middle finger to the Vercel guys.
On a side note, I find it extremely weird that the current AI era of software development is turning the state of the entire field into a reenactment of Lord of the Flies. Bizarre behavior all around from people who should know better.
