Of course I expect it is vibe coding. It would be insane to code anything by hand these days. But that doesn't mean there is no creative input by the author here.
There's a lot of errors you can miss by coding by hand, even as a seasoned developer. Try taking Claude Code, point it at your repo, and ask it to find bugs. I bet it will.
Claude is actually a crazy good vuln researcher. If you use it that way, your code might just be more secure than written purely by hand.
Depends on what you’re building and whether it’s recreational or not. Complex architecture vs a ui analysis tool, for example. For a ui analysis tool, the only reason you code by hand is for the joy of coding by hand. Even though you can drive a car or fly in a plane there are times to walk or ride a bike still.
I genuinely believe this. Even if you're inventing a new algorithm it is better to describe the algorithm in English and have AI do the implementation.
One reason, beside basic altruism, is so you can put the projects on your resume. This is especially helpful if the project does very well or gets lots of stars.
