Gleek

Gleek is a text-based diagramming tool designed for users who prefer working from the keyboard rather than relying on drag-and-drop interfaces. It enables rapid creation of technical diagrams by converting simple, structured text into visual representations. The primary purpose of Gleek is to streamline diagram creation for developers, analysts, and technical teams who need to document systems and processes quickly and consistently.

Gleek supports a wide range of diagram types, including informal diagrams, UML class diagrams, sequence diagrams, state diagrams, Gantt charts, user journey maps, and entity-relationship diagrams. Users define elements, relationships, and layouts using a concise syntax, allowing them to build and modify diagrams at high speed without leaving the keyboard. The tool automatically handles layout and alignment, reducing manual formatting effort. Because diagrams are defined as text, they can be easily version-controlled, shared, and maintained alongside source code or documentation.
