Unbound Worlds was a genre site created by the Random House publishing company. It was launched on July 18, 2008 under the name Suvudu and renamed in August 2016. It featured content and publications from Random House, Del Rey, and Spectra, as well as some stories originally published in Hyperspace. Nine short stories that were originally published on Hyperspace were republished on the site, later under the tag "Star Wars Shorts." These were The Secret Journal of Doctor Demagol, Labor Pains, Interference, Precipice, Lando Calrissian: Idiot's Array, Fists of Ion, Deader than a Triton Moon, Crossroads, Shades of Gray and Knight Errant: Influx, as well as the article Essential Atlas Extra: The Knight Errant Gazetteer.
In November 2018, Unbound Worlds announced that it would be closed down.
