You're referring to State of Utopia's[1] web browser, currently available here:

https://taonexus.com/publicfiles/jan2026/172toy-browser.py.t... (turn the volume down if you play the included easter egg mini-game as it's very loud.)

10-minute livestream demonstration:

That livestream demonstration is side-by-side with Chrome, rendering very simple pages.

It compiles, renders simple web pages and is able to post.

The differences between cursor's browser and our browser:

    - Cursor's long-running autonomously coded browser: over a million lines of code and a trillion tokens, which is computationally intensive and has a high cost.
    - State of Utopia's browser: under 3000 lines of code.

    - Cursor's browser: does not compile at present.  There's no way to use it.
    - State of Utopia's browser: compiles in every version.  You can use it right away, and it includes a fun easter-egg game.

    - Cursor's browser: can't make form submissions
    - My browser browser: can make form submissions.

I'm submitting this using that browser. (I don't know if it will really post or not.)
