I once had to debug a sporadic problem in a prod system I wasn't familar with, which seemed to be caused by two requests made simultaneously by different users. I could have assembled curl commands but the easiest thing to reproduce and verify the issue was to run a setTimeout(clickSubmit, 5s) in both browser session's consoles. Weirdly niche use case, but something like this extension would've been useful.

You can also copy curl command right from the browser network tab, to recreate the request.

I don't know of a reliable way of calling two separate curl commands at once though. Maybe abusing the shell job system, or learning the 'at' command. It has been a while since I've needed to do something like this.

Why abuse? That's what it's for. I'd just copy paste the curl line into a script file several times and put & at the end of each line.

Then end the script with wait command and run the script.

if curl & curl is too slow, try using gnu/parallel.
