ku is fast, async, modern, little tcp man-in-the-middle proxy library, written in pure Python 3.

Features

Dump data between clients and server
Spoof data in both directions
Drop data selectively
IPv6 Ready (pass upstream_6 for upstreaming ipv6 or enclose ipv6 addr in brackets like [::1] for listening addrs

Is this proxy fast?

TODO

Simple proxy usage:
Try to run this script and open http://localhost:80 in you browser
from ku import ku, tcpsession
from time import sleep

proxy = ku(("localhost", 80, "[::1]", 80), ("g.co", 80))

while 7:
try:
sleep(0.07)
except KeyboardInterrupt:
proxy.shutdown() #proxy creates a thread to async poll for socket events
break #we need to call shutdown() to break the thread loop

Advanced proxy usage:
from ku import ku, tcpsession, Pass, Reject
from time import sleep

class conn(tcpsession):

def __init__(self, client, server, proxy):
self.client = client
self.server = server
self.proxy = proxy
self.id = id(self)
print(F"#{self.id} new conn {client.getpeername()}->{client.getsockname()}::{server.getsockname()}->{server.getpeername()}")

def clientbound(self, data):
print(F"#{self.id} server->client {len(data)}")
print(data)
return Pass

def serverbound(self, data):
print(F"#{self.id} client->server {len(data)}")
print(data)
#return None
#in python None is returned by default, None == Pass

def connection_made(self):
print(F"#{self.id} connection_made")

def connection_lost(self, side, err):
side = 'client' if side is self.client else 'server' if side is not None else 'proxy'
print(F"#{self.id} connection_lost by {side} due to {err}")

print("Starting...")
proxy = ku(("localhost", 80), ("api.ipify.org", 80), conn)
print("Started")

while 1:
try:
sleep(0.07)
except KeyboardInterrupt:
print("Shutting down...")
proxy.shutdown()
print("Exiting...")
break
