LivePlay vs undb

LivePlay is a free desktop audio playback app for live shows, designed for live sound operators managing cues. Playlists and cart buttons support cue groups, fades, loops, crossfades, and next-cue actions. Cues can route to channels on one or more audio interfaces. Mixing and monitoring tools include audio buses, EQ, gate, compressor, auxiliary sends, output meters, loudness targets, and a master limiter. Playback control works through mouse, touch, keyboard, MIDI, HTTP, and WebSocket. Media can be added by drag-and-drop or YouTube audio import, with waveform display and LTC timecode output. A desktop controller can connect to a local or remote audio server over a network. LivePlay runs on Linux, macOS, and Windows and is released under AGPL-3.0-only. The Free plan costs nothing with all features and no licence fees, subscriptions, or paywalls. Remote control uses plain HTTP and WebSocket; installers are unsigned and macOS builds are not notarized.
