**mitmproxy** is an SSL-capable man-in-the-middle proxy for HTTP. It provides a
console interface that allows traffic flows to be inspected and edited on the
fly.

**mitmdump** is the command-line version of mitmproxy, with the same
functionality but without the user interface. Think tcpdump for HTTP.

Complete documentation and a set of practical tutorials is included in the
distribution package, and is also available at mitmproxy.org_.
