If you're going to "Show HN" you should show something. This just a hastily-extruded [1] landing page with no details.

Also, using an agentic framework and writing code by hand "a lot of the time" does not count as "from scratch".

Acid3 is 100 tests but to have a browser that works on any real percentage of the internet you need to pass the over 52000 tests and nearly two million subtests [1] that make up the Web Platform Tests [2]

This is like the difference between a college degree and passing a spelling test.

Not to mention this site is clearly vibe coded and has a vague call to action and no source code available thus indicating possible vaporware.

Faster than chrome and 100% clearance of acid3 is certainly interesting, and a great achievement for a solo dev, good job!

I’d love to see something entirely FOSS dethrone the big corp browsers, hope that’s the goal here.

Your own engine?! Wow, that's incredible. Is this gonna be like Servo where people can build a browser around this, or will it be a standalone browser?

I recently switched from Arc to Helium but it's still Chrome with different paint. When I was using Opera 12, it was the most standards-compliant browser so it became my main. What are the goals for cwbrowser (and is the name permanent)?

Modern browsers should no longer score 100 on Acid 3 though.

>By April 2017, the updated specifications had diverged from the test such that the latest versions of Google Chrome, Safari and Mozilla Firefox no longer pass the test as written

lots of questions for HN folks here from a noob dev

- how exactly do you go about writing your own browser engine

- what specs are you supposed to follow

- how do you measure or determine if your browser engine is compliant

- how long do you think such a task would take (no AI / with AI)

- how do you test something like this?

What's the Speedometer 3.1 [0] rating for that browser paired with an M5?

Awesome work! Can't wait for it to land.

What license will you release under?

Nice. Will you also release a version without Javascript (and without css)?

Hello, how does cwbrowser compare with Lightpanda?

Super cool! Any plans to release it for Linux? Would love to test it but I have no Mac unfortunately

how much of it was vibe coded?

This is cool! And as someone else who's been building their own browser engine: welcome to the club!

Do you have WPT tests results, and/or screenshots of it rendering real websites?

i'm assuming this is written with LLMs given the writing on that page and the nature of the other "products" on that website. i would not call that hand-written, as the page does in the second paragraph

Huh, cool, let me know when it's available. I like trying out alternative browser engines every now and then.

closed source?

The whole thing looks like a giant AI slop

What's the goal? Did you learn anything interesting?

No source code, no binary, just a page with some claims about code that might even exist.

Eh.

In terms of engines, Fastrender, by cursor, is AI generated in rust. Don't know why no one's picked that up and run with it yet.

Congrats. I’d love a very agent friendly browser by the way
