About

Dia is an open-source diagramming application that allows users to create a wide range of structured diagrams such as flowcharts, network layouts, and UML designs. Compatible with Windows, Linux, and Mac OS X, Dia offers downloadable shape libraries and scripting options. It is licensed under GPLv2 and includes resources like documentation, bug trackers, and community support.

About

Diagram AI is a browser-based diagramming application that turns natural-language prompts into editable diagrams. Users can create flowcharts, sequence diagrams, cloud architecture maps, class diagrams and runbooks, then revise labels, hierarchy and layout in an interactive canvas or prompt the AI to restructure a draft. The editor accepts PDFs, images and text as context, supports automatic layout adjustments, and keeps version history that can be restored. Diagrams can be exported as XML, SVG or PNG for documentation and presentations. The free plan includes one use per day and excludes file uploads. Pro and Plus plans add monthly credits and contextual file uploads, with higher credit allowances on Plus. The service is intended for product, engineering and operations teams documenting workflows, systems and architecture.
