"So why do you think a 10 kLoC vibecoded codebase will be any good engineering-wise?"

I've been coding a side-project for a year with full LLM assistance (the project is quite a bit older than that).

Basically I spent over a decade developing CAD software at Trimble and now have pivoted to a different role and different company. So like an addict, I of course wanted to continue developing CAD technology.

I pretty much know how CAD software is supposed to work. But it's _a lot of work_ to put together. With LLMs I can basically speedrun through my requirements that require tons of boilerplate.

The velocity is incredible compared to if I would be doing this by hand.

Sometimes the LLM outputs total garbage. Then you don't accept the output, and start again.

The hardest parts are never coding but design. The engineer does the design. Sometimes I pain weeks or months over a difficult detail (it's a sideproject, I have a family etc). Once the design is crystal clear, it's fairly obvious if the LLM output is aligned with the design or not. Once I have good design, I can just start the feature / boilerplate speedrun.

If you have a Windows box you can try my current public alpha. The bugs are on me, not on the LLM:
