Proxelar

Abstract

1. Introduction

Proxelar A scriptable local traffic workbench for HTTP, HTTPS, and WebSocket debugging. Capture, inspect, intercept, replay, and rewrite traffic from your terminal or browser.

Proxelar is a single-binary MITM proxy for developers who need to see and change what an app is doing on the wire without running a full security suite.

Proxelar is intentionally developer-oriented: terminal-first, scriptable, Rust-native, and usable as a CLI tool or as the proxyapi library.

2. Objective

Scriptable local traffic workbench for inspecting, intercepting, replaying, and rewriting HTTP/HTTPS and WebSocket traffic.

This project demonstrates how Rust can be applied to a real-world Cybersecurity & Ethical Hacking problem.
