That doesn’t really address much of the criticism in this thread. No one is shocked that it’s not as good as production web browsers. It’s that it was billed as “from scratch” but upon deeper inspection it looks like it’s just gluing together Servo and some other dependencies, so it’s not really as impressive or interesting because the “agents” didn’t really create a browser engine.

Upon deeper inspection? Someone checked the Cargo file and proclaimed it was just Servo and QuickJS glued together without actually bothering to look if these dependencies are even being used.

In reality while project does indeed have Servo in its dependencies it only uses it for HTML tokenization, CSS selector matching and some low level structures. Javascript parsing and execution, DOM implementation & Layout engine was written from scratch with only one exception - Flexbox and Grid layouts are implemented using Taffy - a Rust layout library.

So while “from scratch” is debatable it is still immensely impressive to be that AI was able to produce something that even just “kinda works” at this scale.

“From scratch” is inarguably wrong given how much third-party code it depends on. There’s a reasonable debate about how much original content there is but if I was a principal at a company whose valuation hinges on the ability to actually deliver “from scratch” for real, I would be worried about an investor suing for material misrepresentation of the product if they bought now and the value went down in the future.

Thanks for the feedback. I agree that for some parts that use dependencies, the agent could have implemented them itself. I've begun the process of removing many of these and developing them within the project alongside the browser. A reasonable goal for "from scratch" may be "if other major browsers use a dependency, it's fine to do so too". For example: OpenSSL, libpng, HarfBuzz, Skia.

I'd push back on the idea that all the agents did was glue dependencies together — the JS VM, DOM, CSS cascade, inline/block/table layouts, paint systems, text pipeline, chrome, and more are all being developed by agents as part of this project. There are real complex systems being engineered towards the goal of a browser engine, even if not fully there yet.
