So tailscale client, the apps you actually download are open source. What’s not open source is the server side code.

Because the interface of tailscale is publicly known and available, someone went and made an open source server side version compatible with tailscale clients.

What’s tail scale?

It’s an easy to use VPN. I can expose just my server to the vpn and my community can easily gain access.

100% not a cost optimized way to host, but much more about balancing cost vs manual maintenance.

Thanks!
