## What it is
NPS is a lightweight, high-performance intranet penetration (reverse proxy/tunnel) server written in Go, supporting TCP, UDP, HTTP(S), SOCKS5, P2P, and more. It includes a web management UI for configuring tunnels, clients, traffic stats, and features like compression, encryption, and bandwidth limits.

## Use cases
- expose a local web server behind NAT to the internet
- access home network devices remotely via SSH tunnel
- debug local payment callback endpoints from external services
- set up a SOCKS5 proxy to reach an internal network
- remote desktop access to a machine behind a firewall
- run internal DNS resolution through a tunnel
- manage multiple tunnel clients through a web dashboard

## When to choose
- you need a self-hosted ngrok alternative with a web UI
- you need many tunnel protocols (tcp, udp, http, socks5, p2p) in one tool
- you want multi-user management, traffic stats, and bandwidth limiting
- you need cross-platform deployment including NAS devices as a system service

## When to avoid
- you only need simple ad-hoc port forwarding without a management server
- you need a project with frequent active development and recent commits
- you require managed cloud tunnels with zero server setup
- GPL-3.0 licensing is incompatible with your usage

## Facets
- artifact type: application
