So I read a whole bunch of text trying to figure out what this thing is...

Then I see the following line in the 'How it compares' section:

"Self-hostable server (open source)": ngrok->No, Cloudflare Tunnel->No, Tailscale->No, Bitbang->Yes

...and I'm like, "It's Open Source Tailscale!"

And now I "get it"! (you know, epiphany, profound enlightenment and all that!) :-)

(Well, it's an open source alternative to Tailscale, to be more precise, and an excellent one at that!)

Great work, Rich LeGrand!

(Another step forward for open source!)
