## What it is
QupZilla is a lightweight, cross-platform web browser built with Qt and QtWebEngine, written in C++. The project was renamed to Falkon and moved to KDE infrastructure, so this repository is no longer actively developed.

## Use cases
- browse the web with a lightweight Qt-based browser
- use a cross-platform browser on Linux, Windows, and macOS
- find a KDE-integrated alternative browser (Falkon)
- self-build a minimal QtWebEngine browser from source

## When to choose
- you want a lightweight Qt-based browser and are fine using the successor Falkon
- you need a browser that integrates well with KDE desktop environments
- you want to study or fork a C++/QtWebEngine browser codebase

## When to avoid
- you need a browser with current security patches and updates
- you expect active upstream development or community support
- you need modern browser features like latest Chromium engine versions

## Facets
- artifact type: application
- maturity: abandoned
- function: gui
- domain: web-development, cross-platform, developer-tools
