Bun has completely changed my outlook on the JS ecosystem. Prior to Bun, there was little focus on performance. Now the entire space rallies around it.

Congrats to Jarred and the team!

Taking a look now - thanks!

I'll take a look - not sure what's going on. I'll remove it from the README for now since it's not working in the demos.

Thank you for letting me know!

They are approximations but Ghostty has intentional effort towards correctness, more than I've seen from other terminal emulators.

Agreed. I removed "not a JavaScript approximation of one" from the README.

It should work! Our demo may not (as I haven't tested it, so don't want to advertise it).

Added it to the README! Thanks again :)

See the comparison: https://github.com/coder/ghostty-web?tab=readme-ov-file#comp...

Ghostty has much better VT100 compatibility. It should have much better performance as well once we optimize.

Let me know if you encounter any issues! I'm working on performance benchmarks now.

Will do this!

That would be great!

`npx @ghostty-web/demo@next` starts an HTTP server on `localhost:8080`, so you could just wrap a basic Dockerfile with NPM installed (and maybe a variety of fun Linux tooling, ala vim).

Feel free to shoot me an email: kyle@coder.com. I'll happily add it to the README.

It's tricky to do without a compute environment.

We can easily make a browser shell that let's people run basic commands, but presumably most want to try `vim` and other commands they'd typically invoke.

I'd have to let Mitchell answer this accurately.

Considering the native Ghostty does, I _think_ the answer would be yes? I might tinker around with this and let you know.

Awesome. If you happen to integrate it and find any bugs, please give us a shout!

They could certainly compile Ghostty and link into it from Rust. I couldn't imagine it'd be that large of an undertaking.

Yup, that's the idea!

Neat. I'll take a look. Thanks Syrus!

We spent little time on performance so far, this is more of a POC that will hopefully become a drop-in replacement for xterm.js over time.

I'll swap it over to the new RenderState API and post some benchmarks!

Many kudos to y'all, we were shocked how simple it was to hack this together.
