I kinda wish I could look at the code, but it's not open source and the frontend sources are minified/obfuscated, but it's long and looks like it's using React and a css-in-react approach, which also generates a ton of code.
The two biggest issues I can think of with this approach is performance and security, with the first one only being a problem if you "make it", and the second one being too often ignored with or without vibe coding.
- can't be maintained over time, gonna need to replace it
- mostly simple/basic furniture
- out of place in any existing environment
- easy to break (cardboard tables!)
Sometimes that's all you need though.
