I hope this works out! Using fiddler us such a frustrating experience. The documentation is practically non existent and the ux is atrocious, and as far as I can tell the closest thing to a manual is a paid ebook by the developer (I was so pissed when I discovered this). I would be very happy to have an open source alternative!

Me too :-). I built this myself in large part because of frustrations with Fiddler. It was an amazing tool at the time, but it hasn't aged well imo...

Hopefully this is your open source alternative - give it a go, let me know if there's something Fiddler does for you that HTTP Toolkit doesn't!

If you think Fiddler sucks get a Mac and try using the tools available there like Charles Proxy. Ugh.

Curious about this comment. I'm a Mac user and a Charles user. I find it to be a great tool. Why the negativity?

It's extremely hard to use compared to something like Fiddler, especially when you are doing more than just tracing.

https://proxie.app/ Works pretty well IMO.

Give Proxyman (https://proxyman.io/) a try, which is a better alternative for Fiddler and Charles Proxy.

I don't mind Fiddler, and $15 dollars for a book on a free, incredibly powerful, tool is a bargain IMHO.

What bothers me is not the price, it's that the only documentation available is an ebook that one of the developers wrote as a side project. The tool is very powerful, but it's a nightmare to use, and it doesn't matter how powerful it is if you spend more time struggling with the software than fixing the problem you have that requires it in the first place. I'm just happy that someone is attempting to create an alternative with a focus on usability and cross platform support.

Yeah fair, Fiddler is definitely well...fiddly, and a bit dated as well.

Agree that it's good to see new alternatives.

It may be interesting to have a rpm package

Didn't try it yet but the promise is amazing.
