Dillo是一款小巧的网页浏览器，遵循GPL。用C语言编写，使用了GTK+ toolkit，该浏览器特别适合运行于老计算机，以及嵌入系统。

由于GTK+2的功能变更很大，不符合Dillo「短小精悍」的需求，所以Dillo转向以FLTK作graphic toolkit。目前porting到FLTK的工作已经近乎完成。一些UNIX/Linux发行版本，包括Debian、RedHat、NetBSD等，有Dillo的安装包，一些小型的Linux系统，包括Damn Small Linux、Feather Linux，将Dillo作为主力浏览器。

Dillo is a minimalistic web browser particularly intended for older or slower computers and embedded systems. It supports only plain HTML/XHTML (with CSS rendering) and images over HTTP; scripting is ignored entirely. Current versions of Dillo can run on Linux, BSD, OS X, IRIX and Cygwin. Due to its small size, it is the browser of choice in several space-conscious Linux distributions. Released under the GNU General Public License, Dillo is free software.
