QupZilla is a free and open-source web browser, intended for general users. It allows seamless integration[clarification needed] 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[clarification needed] 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[clarification needed] 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]
