## What it is
OpenP2P is a lightweight, open-source P2P networking tool written in Go that connects devices across NATs using UDP/TCP hole punching, UPnP, and IPv6, with relay through shared community nodes. It can run at the application layer or with a TUN driver to form an SD-WAN-style private network.

## Use cases
- access office Windows remote desktop from home
- SSH into a home Linux machine behind NAT
- remotely access a NAS without a public IP
- connect to internal ERP systems remotely
- view remote security cameras over P2P
- build a private mesh network between devices
- play multiplayer games across NATs

## When to choose
- you need free NAT traversal without renting a public-IP server
- you want a tiny cross-platform binary supporting many CPU architectures
- you're willing to share bandwidth in exchange for free relay nodes
- you need encrypted tunnels (TLS 1.3 + AES) with TOTP-authorized relays

## When to avoid
- you don't want to contribute bandwidth to a shared public network
- you need guaranteed throughput or SLAs for production traffic
- your organization forbids third-party relay infrastructure
- you need a full-featured commercial VPN or SD-WAN solution
