## What it is
VpnHood is an open-source, cross-platform VPN client and server built entirely from scratch in C#/.NET, designed to be undetectable by deep packet inspection and VPN-blocking firewalls. It includes a free VPN service (VpnHood! CONNECT), a self-hostable client/server (VpnHood! CLIENT/SERVER), and modular NuGet components for developers building custom VPN apps.

## Use cases
- bypass deep packet inspection and VPN-blocking firewalls
- circumvent internet censorship in restrictive countries
- self-host a personal VPN server with zero network configuration
- split tunnel traffic by app, IP, domain, or country
- disguise VPN traffic as ordinary web browsing
- build a custom branded VPN app using .NET components
- protect privacy and hide IP address on public networks

## When to choose
- you need a VPN that evades DPI and advanced firewalls
- you want a free VPN with no traffic or bandwidth limits
- you want to self-host a VPN server without admin privileges or network setup
- you need cross-platform support across Windows, Linux, Android, and iOS
- you're a .NET developer wanting to build or extend VPN applications

## When to avoid
- you need a battle-tested, widely audited VPN like WireGuard or OpenVPN for enterprise use
- you require WireGuard/OpenVPN protocol compatibility with existing infrastructure
- you need support for platforms outside Windows, Linux, Android, or iOS
- you want a fully free desktop experience without premium keys (CONNECT on Windows/Linux has no free servers)
