## What it is
Quantumult X is a network proxy and traffic manipulation tool for iOS, rebuilt from scratch with support for TUN-based traffic, HTTPS MitM decryption, and HTTP request/response rewriting. It offers rule-based routing, custom DNS configuration, and compatibility with protocols like Shadowsocks and V2Ray websocket.

## Use cases
- route traffic through proxy servers with custom rules on iOS
- decrypt and rewrite HTTPS traffic with MitM
- analyze HTTP requests and responses including bodies
- configure custom DNS with IPv6 and custom ports
- filter UDP traffic by destination port whitelist
- use V2Ray websocket over shadowsocks

## When to choose
- you need an advanced proxy client on iOS with fine-grained routing rules
- you want to intercept and rewrite HTTP/HTTPS traffic on a mobile device
- you need per-server health check URLs and detailed policy route history

## When to avoid
- you need a free open-source solution with a clear license
- you want a cross-platform proxy tool for desktop or Android
- you prefer simple one-tap VPN apps without complex configuration
