Falkon is a KDE web browser using QtWebEngine rendering engine, previously known as QupZilla. It aims to be a lightweight web browser available through all major platforms. This project has been originally started only for educational purposes. But from its start, Falkon has grown into a feature-rich browser.
Falkon has all standard functions you expect from a web browser. It includes bookmarks, history (both also in sidebar) and tabs. Above that, it has by default enabled blocking ads with a built-in AdBlock plugin.
The very first version of QupZilla has been released in December 2010 and it was written in Python with PyQt4 bindings. After a few versions, QupZilla has been completely rewritten in C++ with the Qt Framework. First public release was 1.0.0-b4.
Until version 2.0, QupZilla was using QtWebKit. QtWebKit is now deprecated and new versions are using QtWebEngine.
Since version 3.0, QupZilla is no longer developed and new version are released with Falkon name as a KDE project.
