Deckadance is a DJ mixing application originally developed by Belgian software company Image-Line, the makers of FL Studio. The project traces its origins to a late-1990s Image-Line product called FruityDJ and was rebuilt with DJ and programmer Arguru before its first official release in May 2007 for Windows. After Arguru's death later that year, development continued with Image-Line's in-house team, with version 1.72 adding native Mac OS X support in 2010 and a major OpenGL-based rewrite arriving as Deckadance 2 in April 2013.

The software runs as a standalone DJ console or as a VST plugin inside hosts like FL Studio, Ableton Live, and Cubase, which made it distinctive among DJ tools of its era. It ships in House and Club editions, with the Club edition adding timecoded vinyl and CD control. Notable features include a two-channel mixer with three-band EQ, beat detection and sync, a built-in sampler with eight banks for beat-matched loops, the GrossBeat-style ReLooper for rearranging samples on the fly, internal effects (low-pass, high-pass, band-pass, notch, phaser, echo, lo-fi), and broad MIDI controller mapping with autolearning.

Image-Line sold Deckadance to Gibson in 2015, after which it was marketed under the Stanton brand alongside Stanton's hardware DJ controllers, with version 2.72 released in January 2017. Ownership passed to inMusic Brands in 2020 when inMusic acquired Stanton from Gibson.
