I've created yet another HTTP proxy analyzer. I was unhappy about the subscription models of available products for basic features like replay and saving as HAR... so here is another way in a GPL license.
I know better tools aimed at security exists, but I needed a simpler one.
It is an electron app (yeah I know) for making it multi-platform and not yet signed for releases, so I suggest to use the dev install for now.
Cheers
