Tailscale is great, but it's not something that should be shouted from the rooftops.
I use tailscale with nginx / pihole for my home services BUT there will be a point where the "free" tier of their service will be gutted / monetized and your once so free, private service won't be so free.
Tailscale are SAAS (software as a service), once their venture capital funds look like their running dry, the funds will be coming from your data, limiting the service with a push to subscription models or a combination.
Nebula is one such alternative, headscale is another. Wire guard (which tailscale is based on) again is another.
I still use it, the service is very handy (and passes the wife test for ease of use)
Probably some tinfoil hat level of paranoia, but it's one of those situations where you aren't in control of a major component of your network.
