masktunnel 1.1.2

HTTP MITM proxy with browser fingerprinting (CFFI backend)

MaskTunnel Python Bindings

Python bindings for MaskTunnel — an HTTP(S) MITM proxy that adapts its browser fingerprint based on the request User-Agent.

This package wraps the Go implementation and exposes a Python-friendly API.

Overview

MaskTunnel is an HTTP proxy that dynamically changes its fingerprint to mimic real browsers (Chrome / Firefox / Safari / Edge) according to the User-Agent header in requests.

Key capabilities:

• Browser-like TLS fingerprints (JA3 / JA4)
• Browser-like HTTP/2 fingerprints (e.g. Akamai-style settings and frame patterns)
• Automatic selection based on User-Agent
• Optional response JavaScript injection
• Optional upstream proxy chaining

Installation

Using pip (Recommended)

pip install masktunnel

Build from source (sdist)

Building from source requires:

• Python 3.9+
• Go toolchain
• A C toolchain suitable for building Python extensions

Quick Start

Run a proxy server

from masktunnel import Server

server = Server()
print(f"Proxy running at: {server.addr}")

# Blocking; run in a thread if needed
server.start()

Use CLI

After installation:

masktunnel server --port 8080

API

Server

Create a server with options:

from masktunnel import Server, ServerOptions

opts = ServerOptions(
	port="8080",
	username="",
	password="",
	payload="",
	upstream_proxy="",
	user_agent="",
	verbose=0,
)

server = Server(options=opts)

Common operations:

server.start()
server.stop()
server.reset_sessions()

Notes

• The native module is generated at build time into masktunnellib/.
• Prefer installing wheels when available; building from source depends on the local toolchain.
