Or maybe cheapskates, since technically you&#x27;re supposed to buy Charles after a 30-day trial (which didn&#x27;t attempt to enforce itself in my experience.)  I like Fiddler2 on Windows, and I almost had it working well on Wine&#x2F;Linux, but had some issues with SSL.  I should try mitmproxy for the SSL and Fiddler for the UI, but lately I haven&#x27;t needed a proxy.
