I just use wireguard that's built in to opnsense. Am I missing out on something ?

I’ve been using Tailscale because I like the business model they’ve been pushing. They’ve also followed through with that, expanding what the free tier of their service offers instead of restricting it more.

Although possibly biased, Tailscale has a write up comparing the two and the conclusion is that both are good at accomplishing their goals. If you have a technology or business preference, it could mostly come down to that. https://tailscale.com/compare/zerotier/

I've been using secret option 3- netbird. Kernel wireguard support, completely self hostable, and very active development.

Tailscale was the first one I tried and it has worked great for me. If I run into issues maybe I'll look at switching.

Tailscale "just works". Since I've set it up I've never really thought about using anything else. Adding new devices is seamless.

I usually just VPN to my routers if possible. Point to point is feels more reliable than a hole-punching mesh or proxy. On the other hand, this seems to create an end-to-end secure tunnel.

I’ve just been trying both and the Tailscale web dashboard is a lot more polished. Tailscale also uses wireguard instead of something proprietary. But I’m wondering if the zerotier iphone app might use less battery because I’ve heard tailscale has a problem with that.

I use both, mainly Tailscale because it should be faster because it is Wireguard based, but ZT always on as well as a backup.

I started with Zerotier. But at the time Zerotier didn't have exit routes, tailscale did so I tried that and haven't bothered looking at Zerotier since.

I don't know if Zerotier introduced that feature but I like that tailscale uses wireguard.

You can use all functions from tailscale in free tier and its simple and quick.

Tailscale comes in my Synology packages and just works. Haven't looked at zerotier yet.

I first tried zerotier but ran into some weird issue...don't recall what it is now....and then tried tailscale and was up and running in like 15 mins. But I see others have had the absolutely opposite experience from mine where tailscale wouldn't work and zerotier would. I think they're both great products.

I tried and zerotier and didn't understand it, so use tinc. My own network that meshes and is only my servers

I use zero tier just because I’m a noob and was unable to make tailgate work as a docker container, but Im testing now twingate and works pretty well.
