QupZilla is a free and open-source web browser, intended for general users. It allows seamless integration with users' desktop environments and has several distinguishing features. QupZilla is licensed under GPLv3.


QupZilla makes use of Qt WebEngine[3] to support modern web standards.[4] Additional effort was put into seamless integration of the browser with the native look and feel of users' desktops.[5] Some additional features of the browser include the integration of history, web feeds and bookmarks in a single location, the ability to take a screenshot of the entire page, and an Opera-like "Speed dial" home page.[6] It is reported to consume fewer system resources than the major general purpose browsers like Mozilla Firefox and Google Chrome.[7]

QupZilla uses the Qt cross-platform application framework and offers an optimized built-in AdBlock. By default this adblocker whitelists the web page of QupZilla's main search engine, Duckduckgo. A "portable" (no installation) version for Windows platforms exists. QupZilla is also distributed in the PortableApps format.[8]


QupZilla v1.7.0 passed Acid3 test.

The project was started as a research project in 2010. The first preview release, written in Python (using PyQt library), was ready by December 2010.[9] In 2011 the source code was rewritten in C++ with a goal to create a general purpose portable web browser, with the initial target being seamless integration with the desktop environment's look and feel of Microsoft Windows and Linux.[10] Version 1.6.6 (May 2014) still supported Windows 2000.[11]

On 30 March 2016 QupZilla 2.0 was released. It marked the transition from QtWebKit to Qt WebEngine.[3]
