What do you consider "serious", as that seems to be the main differentiator here. I know plenty of serious (multiple years of development and users, and began prior to LLMs) projects that have devs using LLMs for development.
I see. I would not consider these to be serious projects.
I'm sure they give people joy, and contain some decent problem solving, but they are both small extensions to existing software, and are not really solving interesting new problems or creating their own systems.
The size of the project is not what matters. It's the systems it includes and how complex they are.
Actually, that raises a question: are the more complex systems in this collection of projects vibecoded or programmed by a human? Which parts are you aware of that invlude LLM output?
