The world's most advanced open-source DJ software for professional live mixing and broadcasting.
Mixxx is a high-performance, community-driven digital DJ system built on a C++ and Qt framework, designed to provide professional-grade tools for live mixing, broadcasting, and recording. As of 2026, Mixxx continues to lead the FLOSS (Free/Libre Open Source Software) audio market by offering a feature-rich alternative to proprietary solutions like Traktor, Serato, and Rekordbox. Its technical architecture utilizes the SoundTouch library for high-fidelity time-stretching and pitch-shifting, while its modular library system is backed by a robust SQLite database for lightning-fast track indexing across massive music collections. Mixxx stands out for its extensive MIDI and HID controller support, allowing users to map virtually any hardware interface using a flexible JavaScript-based scripting engine. The software is optimized for low-latency performance on Linux, macOS, and Windows, making it a critical tool for performance-focused DJs who require deep customization, privacy, and stability without recurring subscription costs. In the 2026 landscape, Mixxx has integrated advanced AI-driven stem separation (experimental) and refined its internal broadcasting stack to support modern high-efficiency codecs, ensuring its relevance in both underground club scenes and global digital radio environments.
