GeekTool

GeekTool is a macOS application that lets users embed dynamic content directly onto their desktop. It provides four distinct modules—Log, Script, Image, and Web—each designed to retrieve and display information in a customizable way. The Log module monitors file updates, the Script module runs user‑provided scripts and shows their output, the Image module cycles through local or remote pictures, and the Web module renders full web pages or HTML generated by scripts.

The tool is aimed at users who want to personalize their workspace with live data, such as system statistics, network graphs, or photo slideshows, without opening separate applications. Its modular approach allows flexible combinations of text, images, and web content, all refreshed automatically according to user‑defined intervals.
