Flowdia Diagrams

Flowdia is an easy-to-use diagram tool that lets you quickly create professional flowcharts, mind maps, BPMN, network and server layouts, Cisco diagrams, rack diagrams, UML activity/sequence diagrams, business processes, and more. It’s designed for speed: connect shapes by selecting start and end points, add lanes to swimlanes, and add subtopics to mind maps with the + button. Mind map sub-topics auto-position but can be moved as needed.

Flowdia supports exporting diagrams to PNG, JPG, PDF, and SVG (SVGs can be opened in Microsoft Visio), and it can import custom PNG/JPG images. It covers a wide range of diagrams and includes a BPMN shape selector to change activities, events, and gateways. Shapes resize without quality loss, and you can customize backgrounds, text color, and font size. Free version limits include: 4 files, 1 page per diagram, no page removal/duplication, and watermarked exports.
