Is SmartDefrag converted to OpenSource or are there two apps?

i'm not sure whats about iobit smart defrag and smart defrag (opensource).
i just need to know, to clear if the continents biggest tech site/magazine should add or replace the other.
the first one is 3-4y old on their site and i try to put the portable opensource there...
but i need to come clear to them, now its confusing.
i recommend nice apps from here, my fav.
thx
