HTTP/TCP reverse tunnel solution through SSH remote port forwarding
The pgrok is a multi-tenant HTTP/TCP reverse tunnel solution through remote port forwarding from the SSH protocol. This is intended for small teams that need to expose the local development environment to the public internet, and you need to bring your own domain name and SSO provider. It gives a stable subdomain for every user and gated by your SSO through the OIDC protocol. Think of this as a bare-bones alternative to the ngrok's $65/user/month enterprise tier.
HTTP(S)/WS(S)/TCP Tunnels to localhost using only SSH
...You can also use Docker Compose to setup your sish instance. This includes taking care of SSL via Let's Encrypt for you. This uses the adferrand/dnsrobocert container to handle issuing wildcard certifications over DNS. SSH can normally forward local and remote ports. This service implements an SSH server that only handles forwarding and nothing else. The service supports multiplexing connections over HTTP/HTTPS with WebSocket support.
Switcher is a proxy server that accepts connections and proxies based on which protocol is detected. Switcher is heavily influenced by sslh. It started out as a learning exercise to discover how sslh worked and attempt an implementation in Go. The result is useful in its own right through use of Go's interfaces for protocol matching (making adding new protocols trivial), and lightweight goroutines (instead of forking, which is more CPU intensive under load).
