Is this actually stock OpenWRT?

I mean is it supported by vanilla OpenWRT image?

I do like the board though.

You can run vanilla if you want. Their Turris OS is just a custom distro with some added userspace niceties. One of the coolest is a snapshot system that reduces "unbricking" the device to just a menu click at bootup.

There are even people who have gotten NixOS running on it, apparently.
