## What it is
sish is an open-source, self-hostable SSH server that provides HTTP(S), WebSocket(S), and TCP tunnels to localhost, serving as an ngrok/serveo alternative. Users connect with plain SSH commands (no custom client), and it supports subdomain routing, TCP aliases, SNI proxying, and load balancing.

## Use cases
- expose a local web app to the internet over https
- self-host an ngrok alternative on my own server
- share a localhost dev server with a teammate via a public url
- expose a tcp service through a firewall using ssh
- create private ssh-accessible tcp aliases for internal services
- route tls traffic by sni to multiple backends
- test webhooks against a locally running application

## When to choose
- you want ngrok/serveo-style tunnels but need to run them on your own infrastructure
- end users should connect with only plain ssh, no client install
- you need http, websocket, and tcp forwarding plus sni routing in one tool
- you want a production-grade multi-tenant tunnel server with key auth and binding policies

## When to avoid
- you just need a quick one-off tunnel and prefer a zero-setup managed service
- you need a gui or managed dashboard for tunnels
- you cannot control dns (wildcard records) or open ports on a server
- you need features like request inspection dashboards or team management beyond sish's console
