Wikispaces was a wiki hosting service based in San Francisco, California. Launched by Tangient LLC in March 2005, Wikispaces was purchased by Tes Global (formerly TSL Education) in March 2014. It competed with PBworks, Wikia, and Google Sites (formerly JotSpot). It was among the largest wiki hosts. Since 2010, Wikispaces had cooperated with Web 2.0 education platform Glogster EDU. Glogster EDU embedded Glogs into Wikispaces services. Due to cost issues, classroom and free-level Wikispaces closed on July 31, 2018, while private Wikispaces closed on January 31, 2019.
