This is an ultra-lightweight web browser powered by the Ultralight web engine embedded in Qt 5 app as a custom webview widget - QUltralight (Qt Ultralight) - a lightweight replacement for Qt WebKit. The project is at very early stage, so it may be unstable.

Qt Ultralight Browser is very lightweight, it uses only 68 MB of RAM after loading the homepage (DuckDuckGo) and it provides GPU rendering on supported hardware:

You can download the latest binary for Windows in the releases. Keep in mind, this is an alfa version, so use at your own risk!

This project is being developed on Windows 10 using Qt 5.14, MSVC 2017 and qmake, but it should also run on Linux and Mac OS, provided that you have downloaded the lastest SDK for your platform. Extract it to ../ultralight folder relative to qt-ultralight-browser, open this project in Qt Creator and run it. Check that the required Ultralight DLL libraries were copied to the build destination.

Contributions are welcome. Let's meet in #app-development channel on Ultralight Discord.
