A dead giveaway that I think it's AI-made (not necessarily a con) is the complexity of the UI and redundant information. Things like the green dot paired with "interface is up". It looks polished though.

It's not hand coded. I've built it because I've needed for my own purposes.

I've tried wg-easy, but I didn't like the docker approach because it implied to dramatically alter my setup. I just wanted something to manage my already existing setup, something simple and effective. And the coding agent was good enough to built quickly what I needed.

Not sure how you could tell that - the entire repo is 4 commits, all within the last 4 hours.
