Fluxzy.Core

A fast, fully streamed MITM engine for intercepting, recording, and modifying HTTP/1.1, HTTP/2, WebSocket, and gRPC traffic over plain or TLS-secured channels.

This package is used under the hood by Fluxzy Desktop, a cross-platform HTTP debugger, and Fluxzy CLI.

Key Features

  • Intercept HTTP/1.1, HTTP/2, WebSocket, and gRPC traffic
  • Act as a system-wide proxy
  • Export sessions as HTTP Archive (HAR) or Fluxzy Archive
  • Choice of TLS providers: .NET native or BouncyCastle
  • Impersonate JA4 fingerprints and custom HTTP/2 settings

Traffic Modification

  • Add, remove, or modify request and response headers
  • Transform request and response bodies
  • Mock or substitute request and response bodies
  • Forward, redirect, spoof DNS, or abort connections
  • Inject HTML snippets into responses
  • Serve a static directory
  • Provide custom TLS certificates per host

Browse all built-in actions and filters.

Supported Proxy Protocols

Protocol Description
HTTP CONNECT Standard forward proxy tunneling for HTTPS traffic
SOCKS5 Full SOCKS5 support with no-auth and username/password authentication
Reverse Proxy Secure (TLS) and plain HTTP modes for backend service proxying
System Proxy Transparent system-wide interception via OS proxy settings

Quick Start

var fluxzySetting = FluxzySetting.CreateDefault(IPAddress.Any, 44344);

fluxzySetting
    .ConfigureRule()
    .WhenAny()
    .Do(new AddResponseHeaderAction("x-fluxzy", "Captured by Fluxzy"));

await using var proxy = new Proxy(fluxzySetting);
var endpoints = proxy.Run();

Console.WriteLine($"Fluxzy is running on {endpoints.First().Address}:{endpoints.First().Port}");
Console.ReadKey();
