NetCaptor是一款使用了Microsoft Internet Explorer的Trident排版引擎的Internet Explorer外壳浏览器。在IE内核浏览器中最早实现了标签式浏览／分页浏览（Tabbed Browsing），它为IE用户提供了一个替代的多标签界面，并附有一系列额外功能。它是一个可在免费模式（部份功能无法使用，界面中也会显示细小的文本广告）或在已注册模式（称为NetCaptor Pro，无广告，所有功能可用）下运行的广告软件／共享软件。

NetCaptor was an Internet Explorer shell that was in development from 1997 to 2005. It used the Trident layout engine of Internet Explorer in conjunction with additional programmed features to create an alternate browsing experience with a tab-based interface and an expanded feature set. It was an adware/shareware program, but its developer released a registration key for free public use once development ceased.
