## What it is
JUCE is an open-source cross-platform C++ application framework for building desktop and mobile applications, with first-class support for audio plug-in formats like VST, VST3, AU, AUv3, LV2, and AAX. Projects can be managed via CMake or the bundled Projucer project-generation tool.

## Use cases
- build a vst3 audio plugin
- create a cross-platform desktop audio app in c++
- develop an audiounit effect for logic pro
- host audio plugins in my own application
- make an ios music app with c++
- build a digital audio workstation gui
- generate xcode and visual studio projects from one codebase

## When to choose
- you need one C++ codebase targeting desktop, mobile, and multiple audio plug-in formats
- you are building audio or MIDI software and want mature audio I/O and GUI tooling
- you want CMake or Projucer-based project generation for Xcode, Visual Studio, and Android Studio

## When to avoid
- you need a lightweight library for a non-audio project where a full framework is overkill
- your project requires a permissive license and cannot accept JUCE's dual commercial/AGPL licensing terms
- you are building a web or server-side application

## Facets
- artifact type: framework
