## What it is
frp is a fast reverse proxy written in Go that exposes local servers behind NAT or firewalls to the internet. It supports TCP, UDP, HTTP, and HTTPS forwarding with domain-based routing, plus a P2P connect mode.

## Use cases
- expose a local web server behind NAT to the internet
- access my home computer via SSH from outside
- tunnel internal services through a firewall
- forward HTTP requests to internal services by domain name
- set up a self-hosted tunnel without a VPN
- expose a local dev server for testing webhooks
- connect to devices on a LAN remotely
- enable HTTPS for a local HTTP service

## When to choose
- you need to expose local services behind NAT or a firewall to the public internet
- you want a self-hosted alternative to ngrok or similar tunneling services
- you need TCP/UDP as well as HTTP/HTTPS forwarding with custom domains
- you want P2P connectivity to avoid relaying traffic through a server

## When to avoid
- you only need a plain load-balancing reverse proxy in front of backend servers (use nginx or HAProxy)
- you need a managed tunneling service with zero server setup
- you require site-to-site VPN connectivity rather than per-service forwarding
