Defold was created by Christian Murray and Ragnar Svensson as a side-project while they were working at Avalanche Studios, and later as a full time business before being acquired by King in 2014. Defold was developed and used internally at King for a few years before the decision was made to make Defold available to developers outside of King. The announcement and release of Defold as a free to use game engine was made at the Game Developers Conference in San Francisco in March 2016. Development has continued with bi-weekly incremental releases of the engine and editor, with a major milestone being the release of the new editor in 2017.

Free to use and developer-friendly

King made the decision to make the Defold source code available in May 2020, and as part of this process, transfer Defold to a software foundation; the Defold Foundation. The foundation works together with industry partners to provide free and open software and services to game developers across the globe.
