## What it is
GotaTun is a userspace WireGuard implementation in Rust, forked from Cloudflare's BoringTun, providing both a library and a standalone tunnel executable. It works with standard wg and wg-quick tooling and targets Linux, macOS, Windows, Android, and iOS.

## Use cases
- run a userspace wireguard tunnel without kernel module
- embed wireguard protocol in a rust application
- use wg-quick with a userspace implementation
- build a vpn client for mobile platforms
- create wireguard tunnels on windows or macos

## When to choose
- you need a portable wireguard implementation in Rust
- you cannot install the wireguard kernel module
- you want to embed wireguard in your own app via a library
- you need cross-platform support including mobile

## When to avoid
- you already have the Linux wireguard kernel module and prefer kernel performance
- you need a full VPN management GUI
- you need OpenVPN or other VPN protocols

## Facets
- artifact type: library
- maturity: active
- function: vpn, networking, cryptography, cli
- domain: networking, security, privacy, cross-platform
- platform: windows, rust, cli
- tags: wireguard, userspace-tunnel, boringtun-fork, tunnel, linux, macos, android, ios
