If you want something similar, you could set up a cheap VPS with your own reverse proxy making sure that all of your connections are secure between the servers and VPS. But it really depends on your situation. If you have an ISP that assigns you a block of static IPv6 addresses, it's fairly easy to then get a domain and direct based on subdomains to those addresses. I'm not lucky enough to have a halfway decent ISP available in my area, so I can't get that or even a reasonably priced single IPv4 address for residential service, so I have to make due with dynamic DNS which makes things more complex. I fortunately don't have an ISP that forces double NAT on me at least. So I have set up a VPS with a reverse proxy and Wireguard VPN tunnel and I use cloudflare as my domain registrar and their DDNS which I update using my OPNSense router which is also the endpoint of the VPN. I've been considering moving to hosting headscale on the VPS instead, but haven't gotten around to it. It really depends on how many servers, his many services, if you have a domain, if you have a VPS or itger server outside of your home network, if your ISP gives static IPs, and you are behind a double nat kind of situation. Also depends a lot on your bandwidth. Having low upload speeds is a common problem especially if you have cable internet service. I'm lucky enough to have symmetrical fiber direct to my modem even if the ISP is way behind and doesn't offer IPv6 other than 6rd which was meant to be a transitional system like two decades ago and is barely functional.
