EtherTunnel gives any local service a real public HTTPS address in one command.
Plug a local MCP server into web AI chatbots, show a client your
work-in-progress live, SSH home, or reach a database — all over a secure
you.ethertunnel.com URL. Self-host it free, or let us run the relay so
there's no server to babysit.
Anything running on your machine can have a public, secure URL in seconds. Here's what people actually reach for it.
The web versions of today's AI assistants will only connect to an MCP server over
HTTPS — which normally means deploying it somewhere first. With EtherTunnel you run
the server right on your laptop, etun up, and paste the
https://you.ethertunnel.com URL straight into the chat. Your tools are
live in the assistant in under a minute, no cloud host required.
On a call, spin up your dev environment, tunnel it, and drop them the link. They watch your edits land in real time — no deploy, no staging server, no "let me push it first."
Tunnel raw TCP to port 22 and reach your machine from any network. No port forwarding, no VPN, no public IP — just a secure connection back to your box.
Give a teammate or a quick integration secure access to a local Postgres, Redis, or internal API over a raw TCP tunnel — without standing up infrastructure for it.
Point Stripe, GitHub, or any webhook provider at your laptop and debug real deliveries as they arrive — instead of redeploying just to see the payload.
Your machine opens a single outbound, encrypted connection to the relay. No inbound ports, no firewall holes, no public IP. The relay does the scary internet-facing part; your daemon just forwards to localhost.
Hits you.ethertunnel.com from anywhere.
Terminates real TLS, routes by subdomain over a multiplexed tunnel.
One etun binary holding an outbound connection open.
Your dev server, API, or any raw TCP service. Untouched.
The daemon dials out over WSS. Nothing listens on your network, so there's nothing to expose or get scanned.
A genuine Let's Encrypt wildcard cert covers every *.ethertunnel.com subdomain. No self-signed warnings, ever.
Tunnel a web app, an API, an SSH box, a database — anything that speaks TCP, multiplexed down one connection.
The etun binary is the same either way. Self-hosting is free forever — you
bring a server with a public IP, a domain, and the time to keep it alive. Hosted means
you skip all of that and start tunneling in about a minute.
