## What it is
pproxy is a lightweight asynchronous tunnel proxy implemented in pure Python 3 asyncio, supporting HTTP, HTTP2, HTTP3/QUIC, SOCKS4/5, Shadowsocks, ShadowsocksR, SSH, and NAT redirect protocols for both TCP and UDP. It can run as a proxy client or server with features like load balancing, traffic filtering, authentication, and system-wide proxy auto-configuration.

## Use cases
- run a local socks5 or http proxy server
- tunnel traffic through a shadowsocks server
- set up a system-wide proxy on macos or windows
- chain proxies with tunnel and jump support
- redirect iptables or pf NAT traffic through a proxy
- load balance traffic across multiple remote proxy servers
- block or filter hostnames by regex patterns
- proxy UDP traffic over quic or http3

## When to choose
- you need a single lightweight tool supporting many proxy protocols
- you want a pure-python proxy with no heavy dependencies
- you need both TCP and UDP tunneling with shadowsocks or ssh
- you want quick CLI-based proxy setup with system proxy integration

## When to avoid
- you need maximum throughput in a high-traffic production environment
- you need a GUI-managed proxy client
- you require protocol features outside its supported list, such as WireGuard or VPN-level tunneling
