## What it is
QSimpleUpdater is an auto-updating library for Qt applications written in C++. It checks a remote JSON definitions file for newer versions, prompts users, and can download and launch installers or emit signals for custom handling, with per-module update support.

## Use cases
- add auto-update to a Qt desktop application
- check for new versions via a JSON file
- download and launch installers when updates are available
- update different modules of an app independently
- implement custom update flows using signals

## When to choose
- you have a Qt 5.15+/Qt6 C++ desktop app needing update checks
- you want a lightweight, embeddable updater with CMake or qmake integration
- you need per-module version checking and configurable install behavior

## When to avoid
- your app is not built with Qt
- you need cross-platform update frameworks with code signing and delta updates like Sparkle or Squirrel
- you need a server-side update management service

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, networking, configuration-management
- domain: developer-tools, cross-platform, desktop-applications
- platform: cpp, cross-platform, windows
- tags: qt, auto-update, updater, version-checking, software-distribution, desktop, macos, linux
