I was excited to try it out so I downloaded the repo and ran the build. However there were 100+ compilation errors. So I checked the commit history on github and saw that for at least several pages back all recent commits had failed in the CI. It was not clear which commit I should pick to get the semi-working version advertised.

I started looking in the Cargo.toml to at least get an idea how the project was constructed. I saw there that rather than being built from scratch as the post seemed to imply that almost every core component was simply pulled in from an open source library. quickjs engine, wgpu graphics, winit windowing & input, egui for ui, html parsing, the list goes on. On twitter their CEO explicitly stated that it uses a "custom js vm" which seemed particularly misleading / untrue to me.

Integrating all of these existing components is still super impressive for these models to do autonomously, so I'm just at a loss how to feel when it does something impressive but they then feel the need to misrepresent so much. I guess I just have a lot less respect and trust for the cursor leadership, but maybe a little relief knowing that soon I may just generate my own custom cursor!

WGPU for render, winit for window, servo css engine, taffy for layout sounds eerily similar to our existing open source Rust browser blitz.

Maybe we ended up in the training data!

I follow Dioxus and particularly blitz / #native on your Discord and I noticed the exact same thing too. There was a comment in a readme in Cursor's browser repo they linked mentioning taffy and I thought, hang on, it's definitely not from scratch, as they advertise. People really do believe everything they read on Twitter.

Great work by the way, blitz seems to be coming along nicely, and I even see you guys created a proto browser yourselves which is pretty cool, actually functional unlike Cursor's.
