## What it is
Brook is a cross-platform programmable network tool written in Go that provides encrypted proxy/VPN functionality with system-level network takeover. It supports client and server-side scripting to control DNS, routing, packet capture, and MITM of HTTP/HTTPS traffic.

## Use cases
- set up an encrypted proxy server to bypass censorship
- route all system traffic through a VPN-like tunnel on any OS
- capture and modify HTTP/HTTPS traffic with MITM
- block ads by controlling DNS resolution
- run a socks5 proxy with zero configuration
- control which applications can access the network
- run a proxy on an OpenWrt router

## When to choose
- you need a cross-platform encrypted proxy with clients for desktop, mobile, and routers
- you want programmatic control over DNS, routing, and traffic at the system level
- you need MITM and packet capture capabilities built into your proxy tool

## When to avoid
- you only need a simple HTTP proxy without encryption or scripting
- you need a GUI-only solution with no paid tiers for advanced features
- you require an audited, widely-reviewed VPN protocol like WireGuard
