First of all — I’ve seen Boxy before, and congratulations on the product you’ve built. It’s genuinely impressive, especially considering how much depth a serious SVG editor requires.

This result is actually the fourth iteration of VectorNest. In previous versions I would build something, then restart from scratch — but always reusing pieces and, more importantly, the learning from the prior attempts. The big leap happened in the last few months, mainly due to an architectural decision (moving to a plugin-based core) and the noticeable improvement in LLM precision, which made iteration much more reliable.

For me this is a side project, so I only dedicate a few hours per day. I started the first iteration less than a year ago, and the current iteration began about four months ago.

I completely understand the anxiety around what LLMs can now produce — but I also think building something robust and production-ready still requires a lot of architectural thinking and long-term iteration.
