QtWeb is a lightweight, Open Source Portable Web Browser designed to run directly from a USB flash drive without installation. This stand alone browser is ideal for users who need a fast, minimal, and privacy respecting way to browse the web on shared or public computers.
Because QtWeb does not require installation and stores almost all data locally within its own folder, it leaves virtually no footprint on the host system, with the exception of downloaded files. This makes it especially useful for privacy conscious users, technicians, and travelers who need a portable browsing solution they can trust.
Built on Nokia's Qt framework and using the WebKit rendering engine; the same engine historically used by Apple Safari and early versions of Google Chrome this portable internet browser delivers reliable standards compliant web rendering in a very compact executable.

What Is QtWeb?
QtWeb is a minimalist web browser created as a demonstration of what could be achieved using the Qt application framework combined with the WebKit rendering engine. Unlike full featured browsers such as Firefox or Chrome, it focuses on speed, simplicity, and portability rather than extensions, accounts, or cloud integration.
The application launches as a single executable and does not modify system files or require administrative privileges. This makes the portable internet browser particularly well suited for use on locked down systems, school or library computers, or environments where installing software is not permitted.
Although development has been discontinued, it remains functional for basic browsing tasks and continues to be used as a lightweight portable browser alternative.
