I am, the UniFi Java blob that runs on MongoDB. I use it for my 802.11ac access points, although not very often.

I really want to move to openwrt on them (not a big fan of how Ubiquiti treats out-of-support hardware), but I’m scared of taking the big plunge of managing them all with a unified interface. There exist projects to do just this, I guess it’s the work to set it all up.
