ABrowse is a web browser for the AtheOS/Syllable operating system. Like Apple's Safari, it uses a port of the Khtml html layout engine. ABrowse's inception and port of Khtml were performed by Kurt Skauen, who also created AtheOS.

The port of Khtml communicates with the operating system's GUI's widget toolkit via a wrapper for the Qt toolkit.

Because of difficulties with the amount of work required to maintain current ports of Khtml on the Syllable operating system, ABrowse's use of the Khtml layout engine shall be dropped by the Syllable Internet Tools Team in favour of the more-portable Gecko layout engine.

Current development is performed by the Syllable Internet Tools team.
