Gleek
FreemiumGleek is a really neat diagram-making tool designed specifically for developers who prefer using their keyboards instead of a mouse. It lets you create all sorts of diagrams – think informal ones, class diagrams, sequence diagrams, state diagrams, Gantt charts, user journey maps, and even entity-relationship diagrams – all without a single click. Gleek uses a simple, intuitive syntax that turns your text descriptions directly into visuals. This makes it super quick to pick up and genuinely easy to use. Plus, it offers some great features like really fast diagramming, keeping track of changes with text descriptions (which is great for version control!), working together live with others, exporting your diagrams in different formats, and even design templates to give you a head start on common diagram types.
