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
