🕳️ funnel

a tunneling solution built with go

expose local services to the internet through websocket connections

⚠️ disclaimer

this tunneling solution is intended for development and testing purposes. while functional, it may not include all security features required for production environments.

funnel is a lightweight tunneling solution that allows you to expose your local development services to the internet. it works by creating a persistent websocket connection between a client on your machine and a remote server.

key features

http tunneling: expose any local http service with a single command
secure connections: supports tls with let's encrypt for secure tunnels
custom subdomains: use your own memorable tunnel ids
automatic reconnection: client automatically reconnects if connection is lost
cross-platform: single binary for linux, macos, and windows

how it works

the flow is straightforward:

the funnel client starts on your local machine and connects to the funnel server
the funnel server registers a unique public url for your tunnel
when a request comes in, the server proxies it through the websocket to the client
the client forwards the request to your local service
the response travels back through the same path
