I started working on FinZot before vibe coding was a thing. It was originally a project to learn rust/wasm. The planning engine is very much not vibe coded. I had too much fun optimizing the engine such that monte carlo trials run trials in ~1ms to have AI write the code. The newer parts of the UI were written by AI. AI has also been amazingly helpful to scale testing.
