## What it is
onetun is a cross-platform, user-space WireGuard port-forwarder written in Rust that forwards local TCP/UDP ports to peers on a WireGuard network. It requires no root access, no kernel WireGuard module, and no system network configuration changes.

## Use cases
- forward a local port to a service on a WireGuard network without installing WireGuard
- access WireGuard-protected services from devices without root access
- expose WireGuard network services inside rootless containers
- connect to a WireGuard peer from IoT or mobile devices that can't run WireGuard
- tunnel TCP and UDP traffic over WireGuard in user space

## When to choose
- you need WireGuard connectivity without root or kernel module installation
- you're running in a rootless container or restricted environment
- you only need port forwarding to specific peers, not a full VPN tunnel
- you want a single static binary or Docker image with no system dependencies

## When to avoid
- you need a full VPN tunnel with routing of all system traffic
- your OS already supports native WireGuard and you have root access
- you need high-throughput forwarding, as user-space networking adds overhead
