Description
Astah UML gives software teams and students a focused tool for UML 2.x modeling. Class, use case, sequence, activity, state machine, component, and deployment diagrams are all available, together with mind maps for early brainstorming.
Every diagram is a view of a shared model, so renaming a class or changing a relationship updates it everywhere it appears.
For AI-assisted work, Astah UML offers AI Chat Copilot and AI-assisted code reverse engineering, both of which connect to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key. A local MCP server lets external AI agents read and work with your models, and conventional reverse engineering turns existing Java, C#, and C++ code into diagrams without an AI service.
Astah UML runs locally on Windows, macOS, and Linux.
Developer: Change Vision, Inc.
Current version: 12.0 (July 2026).
Students can use it free of charge, and a 20-day trial is available for everyone else.
Description
Sankey Flow Show elevates both Sankey diagrams and traditional flow charts to a new level of functionality. You can easily adjust the thickness of the connection lines in your classic flow diagram using just a single slider, or alternatively, utilize a distinct data layer to visualize energy flow, mass flow, or other quantities within your Sankey diagrams. This innovative tool significantly minimizes your workload! Creating visually appealing diagrams with Sankey Flow Show is remarkably simple. Once your diagram is completed, you can modify values in the dedicated data layer without needing to make any manual graphical changes. Experience the speed and simplicity of crafting engaging diagrams. There’s no installation required, and you'll never miss an update since Sankey Flow Show operates directly in your web browser. Share your creations with others, export your diagrams in common formats like svg, jpg, png, and pdf, and easily view or revert to earlier versions. You can also collaborate in real-time, ensuring you remain competitive in your field. With its user-friendly interface and powerful features, Sankey Flow Show is the ideal choice for anyone looking to enhance their diagramming experience.
