frp

frpc | frps [options]

frp (fast reverse proxy) exposes local servers behind NAT or firewalls to the internet. It consists of a client (frpc) on the internal network and server (frps) on the public server.
The tool supports TCP, UDP, HTTP, and HTTPS protocols with features like encryption, compression, and authentication. It enables accessing internal services, SSH tunnels, and web applications remotely.
frp provides a self-hosted alternative to services like ngrok.
