Tailscale has captured mindshare, reminds me some of Cloudflare. There are many solutions out there offering unique value props relative to what Tailscale is doing, and it all comes down to customer needs. I'm not sure how broadly Tailscale has been adopted outside of the dev / HN crowd, so that's always something to dig into.
Let’s just say that as the person who introduced Tailscale within our org, it has been one of the most easiest solutions I ever had to convince my org of. Given the relative intrusiveness of switching a VPN provider (it touches a lot of core infrastructure), I expected a lot more resistance, but everybody was on board immediately.
In all honesty, Tailscale being so good, we never seriously looked at Zerotier. We only evaluated it on paper, not actually tried to use it.
