This was written in zig and built by vercel. That’s the only notable characteristics about this project.
All code agents look the same and this one is no different.
I don't think Zig is that great of a language for this, but it's better than typescript. I don't want to use Vercel software so will pass, but would love to see a more community driven effort.
