I was looking for something like this. I used to use Replit to teach code (even integrated it into discussion sections when I was a TA) but they absolutely destroyed the product with AI vibecoding integrations over the past year.

On Firefox, when I run code that uses input, I get:

> RuntimeError: The service worker for reading input isn't working. Try closing all this site's tabs, then reopening. If that doesn't work, try using a different browser.

Is this a Firefox problem?

It would be great to be able to share an attached terminal as well, as a lot of action happens there when programming.

Pretty cool! Always struck me as odd that the IDE has largely remained single-player for 40 years.

It looks great, but does it have a debugger?

Stepping through loops and visualizing in real time how the variables change is indispensable for teaching how programming in general works.

Organizer of Python Atlanta here. This looks really nice. I’ll share it in our meetup next week. If you want to reach out and maybe give me some pointers feel free to reach out at hello@pyatl.dev

This is awesome! I'm also working on something like real-time collaboration on codebases, but nothing as freehand as this, really inspiring!
