This is an useful tool. I wish there was something similar for desktop applications.

The nice thing about implementing this for the web is that the API you have to record data from (DOM events) is the same no matter what UI toolkit you use on top of it. But on desktop, the ecosystem is more fragmented and would require more ports and quirks to implement a widely compatible bug recorder.

I'm not a fan of webdev, but this is an advantage it has over desktop development.
