Is there a difference between /kbin and kbin?

For example, this magazine is named "/kbin meta" but the description says "Magazine dedicated to discussions about the kbin itself." (emphasis mine.) If you look at https://kbin.pub/en you see both

/kbin is an open source reddit-like content aggregator and microblogging platform for the fediverse.

and

Kbin is a decentralized content aggregator and microblogging platform running on the Fediverse network.

So do /kbin and kbin mean the same thing, and is one of them the more "official" name than the other? Just curious.
