Software engineer here, so I am unsure if it counts but we built a product that's doing ~$500k/year and ~95% of it is vibe coded.
The difference would be, we knew what we were doing (This makes me sleep better at night.), because of pre LLM era experience.
That's impressive How much of the code did you write or fix yourself And has it been a pain to maintain or has AI been pretty good at handling that too?
I wrote under 5% of the code by hand. It was mainly telling the AI to build x and how to build it. With the new Fable 5.1, even the how part is getting replaced.
For this project, the maintaince is not too big of a pain, but we are working on another project where it's an absolute pain. Every PR is like 100k lines change, simple bug fix needs 600k tokens. We are probably doing a choppy job here.
The size of the codebase definitely plays a role.
