Itβs OpenWRT as you said but with their own skin and added features instead of completely spinning it off from the ground just because one has a feature to add as an idea like the native AdGuard Home home you mentioned, this makes sure itβs either continually supported because of OpenWRT or anyone can install the vanilla OpenWRT if support is no longer carried by the manufacturer.
