Brendan Eich ( the creator of JavaScript) was kind enough chime in that it would be impossible for variety of reasons.
Obviously he knows more about this than me, but I think Google could put Dart in there if they really wanted.
WebAssembly is pretty close though.
Internet explorer just didn't provide the same experience as Chrome.
For example if Firefox decides to add Rust support it doesn't mean every other browser needs to support it.
Just a handful of web experiences are going to be exclusive to Firefox. As is having Chrome as the only browser most people use isn't great for innovation.
Most sane HN commenter. Jesus Christ.
Me: Well different browsers could support different features.
HN: NOT LIKE THAT, we want every website to be compatible with everything!
People want different browsers so that chromium doesn't get to enforce their monopoly on web standards but I mean, its already happening. Like, if something runs on chrome and it doesn't run on firefox and is used by a lot of people...
Effectively firefox is ALSO forced to have those chromium features...
Basically the web standards is held hostage by chromium and we need a very heavy migration of large swathes of people away from chrome to something like firefox and that's whats being advocated I suppose.
I use zen / firefox because I also don't want chromium. I mean, idk if I have a particular reason except the above logic that I shared. honestly, idk to be honest.
You simply can't expect to run Roblox games inside of Chrome
Roblox can't generally be used to file your taxes.
But your visiting user created experiences.
The big problem is it's all controlled by one super company .
There's no reason we can't have an open source browser like which allows you to play various games, or run other sandbox applications. These applications could be programmed in a variety of different languages.
In this scenario, whatever I still need Chrome to handle certain important business, but I can use this alternate browser to engage with tons of other content.
Minecraft in a similar vein too.
I was actually thinking of creating a roblox alternative or atleast proposing the idea of modifying luanti which is open source to have roblox esque graphics.
So it would be the open source browser which allows you to play various games in some sense.
If you want sandbox applications, there is libriscv created by legendary fwsgonzo which can run on any device or wasm I suppose
Part of why WebAssembly was successful is that it's a way of generating javascript runtime IR instead of a completely new language + standard library - browsers can swap out their JavaScript frontend for a WASM one and reuse all the work they've done, reusing most of their native code generator, debugger, caches, etc. The primitives WASM's MVP exposes are mostly stuff browsers already knew how to do (though over time, it accumulated new features that don't have a comparison point in JS.)
And then WASM itself has basically no standard library, which means you don't have to implement a bunch of new library code to support it, just a relatively small set of JS APIs used to interact with it.
<script type="module" src="https://pyscript.net/releases/2025.8.1/core.js"></script>
<py-script>
import sys
from pyscript import display
display(sys.version)
</py-script>
Or you can use MicroPython which is much smaller:
<mpy-script>
import sys
from pyscript import display
display(sys.version)
</mpy-script>
I would be interested to see how short the time to run "Hello World" can be with python in a webpage, counting the time to load the whole page without cache.
That being said, I'm also 100% behind the effort to standardize WASM as the cross-platform compilation target of choice.
