I have yet to see any of these that wouldn’t have been far better off self-hosting an existing open source app. This habit of having an LLM either clone (or even worse, cobble together a vague facsimile) of existing software and claiming it as your own is just sort of sad.
I actually came to this realization recently. I'm part of a modding community for a game, and we are seeing an influx of vibe coded mods. The one distinguishing feature of these is that they are entirely parasitic. They only take, they do not contribute.
In the past, new modders would often contribute to existing mods to get their feet wet and quite often they'd turn into maintainers when the original authors burnt out.
But vibe coders never do this. They basically unilaterally just take existing mods' source code, feed this into their LLM of choice and generate a derivative work. They don't contribute back anything, because they don't even try to understand what they are doing.
Their ideas might be novel, but they don't contribute in any way to the common good in terms of capabilities or infrastructure. It's becoming nigh impossible to police this, and I fear the endgame is a sea of AI generated slop which will inevitably implode once the truly innovative stuff dies and and people who actually do the work stop doing so.
