## What it is
3proxy is a tiny, free proxy server written in C supporting SOCKS, HTTP, HTTPS, FTP, and TLS proxying with traffic shaping, port mapping, and accounting. It runs on Windows, Linux, and Unix, with signed package repositories and Docker images available.

## Use cases
- set up a socks5 proxy server
- run a lightweight http proxy on linux
- proxy server with traffic shaping and bandwidth limits
- self-hosted https/tls proxy
- ipv6-capable proxy server
- port mapping and forwarding proxy
- small footprint proxy in docker

## When to choose
- you need a tiny, resource-efficient multi-protocol proxy server
- you want SOCKS5, HTTP, and HTTPS proxying in one tool
- you need traffic shaping, accounting, or IPv6 support
- you want a self-hosted proxy with Docker images or signed packages

## When to avoid
- you need a caching forward proxy like Squid with content filtering
- you need a full-featured load balancer or API gateway
- you prefer a GUI-managed proxy solution
- antivirus false positives on the binary are unacceptable in your environment
