As a ZeroTier basic subscriber was looking to upgrade to the Essential plan. It increased from $5 to $15 overnight, and with no added features.
GL iNet routers do offer ZeroTier and it works great, but with this price increase I'm looking to self-host. ZTNet - Zerotier Web UI seems to do the trick. Any way routers can support this feature? can it be installed as a package and add to the router UI?
