What is Sankey Flow Show?

Sankey Flow Show takes both traditional flow charts and Sankey diagrams to an enhanced level of efficiency and usability. With just a simple slider, you can effortlessly modify the thickness of connection lines in your conventional flow diagrams, or you can take advantage of a separate data layer to represent various flows, such as energy or mass, within your Sankey visualizations. This advanced tool drastically reduces your workload, making it easier than ever to design stunning diagrams. Once your diagram is finished, you can change values in the specific data layer without having to make any manual adjustments to the graphics. Enjoy the fast and straightforward process of creating captivating diagrams that truly stand out. There’s no need for installation, and updates are seamlessly integrated since Sankey Flow Show functions directly in your web browser. You can share your designs with colleagues, export them in popular formats like svg, jpg, png, and pdf, and easily access or revert to previous versions of your work. Real-time collaboration is also a key feature, helping you stay ahead in your industry. With its intuitive design and robust capabilities, Sankey Flow Show is the perfect tool for anyone aiming to elevate their diagramming workflow and creativity. Beyond just enhancing visuals, this platform encourages teamwork and continuous improvement in design projects.

What is Astah Professional?

Astah Professional is a desktop modeling application from Change Vision, Inc. for organizations that design software and systems. It brings UML 2.x, ER diagrams, data flow diagrams, flowcharts, requirement diagrams, CRUD, and mind maps together in one product, which reduces the number of tools a team needs to license and learn. Because Astah stores designs as models rather than drawings, an update made in one place carries through to every related diagram. This keeps design documentation consistent as projects change. Version 12.0, released in July 2026, brings AI into the modeling workflow. AI Chat Copilot and AI-assisted code reverse engineering run on your organization's own API key for OpenAI, Azure OpenAI, Claude, or Gemini, or for an OpenAI-compatible service, so AI usage stays under the contracts you already manage. Local MCP server integration lets AI agents connect to your Astah models. Licenses are available monthly, annually, or as a perpetual license, starting at $11.99 per month. Astah Professional runs on Windows, macOS, and Linux without a separate Java installation, and a 20-day free trial is available.
