I built a free SSH relay for homelab machines behind CGNAT

As most of you know, ISPs don't often provide real ingress-routable IP addresses. So I built a free relay system, that works directly with latch [1], a terminal multiplexer with built in SSH/Mosh/etc.

It's powered by 9 POPs. latch maintains a QUIC tunnel with your relay, and you connect to whichever is closest to you. Wherever you are in the world, you will be able to connect to a nearby relay and be routed to your instance.

latch is written in go: https://github.com/unixshells/latch

You can simply get started by typing: curl -sSf unixshells.com/install.sh | sh

Then, just simply do latch relay register, confirm your e-mail and you're good to go!

You can also access it via our web terminal [2]!

Full disclosure: This is completely free and subsidized by the shells we do offer.
