Yeah, I like that I can just upload a static html and host it there for free, but anything more I dunno. Its all about vendor lock-in with their products.

They did build a browser; it may not be a very compliant or complete browser, or even a useful one, but neither was IE6!

I believe it was basically a broken, non-functioning wrapper around Servo internals. That’s what I’d expect from a high schooler who says “i wrote a web browser”, but not what I’d expect from a multi-billion dollar corporation.

They aren't really a multi-billion dollar corporation. A lot of it is them just pumping up their valuation. Stuff like this proves that in a lot of ways.

Days after the fake story about Cursor building a web browser from scratch with GPT-5.2 was debunked. Disbelief should be the default reaction to stories like this.

It didn't even compile, which makes me consider wether your comment is just ignorant or outright maliciously misleading

I essentially just use them for this and domain DNS/Registrar as their pricing is pretty good for that.

Btw, after I wrote that initial article ("Cursor's latest "browser experiment" implied success without evidence"), I gave it my own try to write a browser from scratch with just one agent, using no 3rd party crates, only commonly available system libraries, and just made a Show HN about it: https://news.ycombinator.com/item?id=46779522

The end result: Me and one agent (codex) managed to build something more or less the same as Cursor's "hundreds of agents" running for weeks and producing millions of lines of code, in just 20K LOC (this includes X11, macOS and Windows support). Has --headless, --screenshot, handles scaling, link clicking and scrolling, and can render basic websites mostly fine (like HN) and most others not so fine. Also included CI builds and automatic releases because why not.

The repository itself is here and should run out of the box on most modern OSes, downloads can be found at the Releases page: https://github.com/embedding-shapes/one-agent-one-browser

The outrageous part of this is nowhere in the blog post or the repository indicates it's vibe coded garbage (hopefully I didn't miss it?). You expect some level of bullshit in AI company's latest AI vibe coding announcements. This can be mistaken for a classical blog post.

Although the tell is obvious if you spent one second looking at https://github.com/nkuntz1934/matrix-workers. That misaligned ASCII diagram, damn.

Why is Cloudflare paying this guy again, just to vibe a bunch of garbage without even checking above the fold content in the README?

The version that was live on GitHub the day they published their blog post was missing compilation instructions, didn't cleanly compile and didn't pass GitHub Actions CI.

The project itself did compile most of the time it was being developed - the coding agents had been compiling it the whole time they were running on it.

Shortly after the blog post they updated the GitHub repo with compilation instructions and it worked. I took this screenshot with it: https://static.simonwillison.net/static/2026/cursor-simonwil...

The "it didn't even compile" criticism is valid in pointing out that they messed up the initial release, but if you think "it never compiled" you have an incorrect mental model.

This project is awesome - it really does render HTML+CSS effectively using 20,000 lines of dependency-free Rust (albeit using system libraries for image rendering and fonts).

Here's a screenshot I took with it: https://bsky.app/profile/simonwillison.net/post/3mdg2oo6bms2...

My understanding is that it doesn't even compile if you clone the repo.

It does now. It didn't on initial announcement day.

It's getting outright frustrating to deal with this.

Fine, random hype-men gets hyped about stuff and tweets about it, doesn't mind me too much.

Huge companies who used to have a lot of good will putting out stuff like this, seemingly with absolutely zero reviews before hitting publish? What are they doing? Have everyone decided to just give up and give in to the slop? We need "engineering" to make a comeback.
