According to the website it's a free limited version, and you can buy upgrades to expand its capabilities. No indication of what the limitations are yet. With the recent price increase to AD (which is something like US$6K3/seat, not counting subscription, IIRC) it's going to be a steep slope unless the free version is REALLY basic. My guess would be they leave out all of the signal integrity stuff, the more advanced design rule capability, a lot of the data management capability, and limit the max PCB size. Their big competition is Eagle first and probably KiCAD second, so as long as the software is robust and easy to use, there's lot of room for them to be competitive even without bringing a lot of the features of AD all the way down to the free option.
