Mixxx
Free open source DJ software for Windows, with updated controller mappings
DJ software for Windows
DJ software for Windows splits into a few clear camps, and the three apps in our catalog show where the lines fall. Mixxx is open source under GPL-2.0-or-later and costs nothing. rekordbox, from AlphaTheta, centers on managing a music library and linking it to DJ equipment. VirtualDJ, from Atomix Productions, is free only for non-professional use, so paid gigs would need a different arrangement.

The first thing to check is licensing. Mixxx is open source, while the other two are proprietary. The second is how much of your workflow lives inside the app: library analysis, playback history, hardware pairing, streaming support. Install size matters less, but it ranges from 115.1 MB for Mixxx to 630.2 MB for rekordbox.
A caution: none of the three has a tier A rating in our catalog, and none carries an ad-free label. All three sit in tier B, so the choice comes down to fit rather than a clear winner.

Best-of lists
Before settling on one, compare what each app asks of your setup. If you own DJ hardware, look at the vendor's own compatibility list to confirm your controller is supported. A smaller install such as Mixxx at 115.1 MB is easier to try on an older laptop, while rekordbox at 630.2 MB needs more room for its library tools.
If you plan to play paid events, read the VirtualDJ terms first. Then load a small set of your own tracks into one app and check how it handles analysis and playback before building a full library around it.
