Data visualization is a great way to simplify and understand complex relationships in process systems. e!Sankey is the perfect tool for that! Sankey diagrams go beyond simple flow charts. Their arrows have a width proportional to the flow quantity and draw attention to the largest flows in the system. Design your Sankey diagrams in the net editor: Just draw arrows and processes to build your diagrams easily. Benefit from a clear entry and unit management, including unit conversions. Use e!Sankey to calculate flow quantities. This makes the generation of Sankey diagrams even more comfortable. -

AltonaLab
AltonaLab
AltonaLab IoT software has a powerful and easy-to-use CAD environment, suitable for the design of complicated diagrams. Please read the documentation and enjoy the exciting world of IoT software! The new connection is established when the user left-clicks with the mouse over the block’s input or output, without releasing the mouse button drag the mouse to the direction of another input/output, and then release the mouse button over it. Double click over the block or click with the right mouse button opens the Parameters editor where every parameter is presented with the separated row. The parameter Name is very important and is unique within the diagram! When the diagram is locked, the application uses this parameter to determine the diagram's size. This is a tricky way to hide all the blocks and contours which are outside the visible area (the area determined from parameters LockedCanvasHeight / LockedCanvasWidth) and only controls from a visible area to be shown.Starting Price: $50 one-time payment -

AVEVA Diagrams
AVEVA
AVEVA Diagrams is a fast, efficient and effective tool for creating and managing your Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), Heating, Ventilation, and Air Conditioning (HVAC) and similar drawings with the assurance that they remain fully integrated with the project database. AVEVA Diagrams is a fast, efficient and effective tool for creating and managing your Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), Heating, Ventilation and Air Conditioning (HVAC), and similar drawings with the assurance that they remain fully integrated with the project database. Using AVEVA’s proprietary database technology; as the diagram is designed, data is logged and stored in a schematic model database. This allows design information to be managed effectively and accessed easily within a secure and shared data-centric environment in the cloud through AVEVA Connect or deployed on-premises as part of our full IE&D solutions. -

SchemaFlow
SchemaFlow
SchemaFlow is a powerful tool designed to enhance AI-powered development by providing real-time access to your PostgreSQL database schema through the Model Context Protocol (MCP). It allows developers to connect their databases, visualize schema structures with interactive diagrams, and export schemas in various formats such as JSON, Markdown, SQL, and Mermaid. With native MCP support via Server-Sent Events (SSE), SchemaFlow enables seamless integration with AI-Integrated Development Environments (AI-IDEs) like Cursor, Windsurf, and VS Code, ensuring that AI assistants have up-to-date schema information for accurate code generation. It offers secure token-based authentication for MCP connections, automatic schema synchronization to keep AI assistants informed of any changes, and a schema browser for easy navigation of tables and relationships. -

Astah UML
Change Vision, Inc.
Astah UML is a UML 2.x diagramming tool for software design, developed by Change Vision, Inc. It covers the core UML diagrams, including class, use case, sequence, activity, state machine, component, and deployment diagrams, plus mind maps. Astah creates models rather than drawings: when you change a model element, every diagram that uses it is updated, so your design stays consistent. AI features include AI Chat Copilot and AI-assisted code reverse engineering, which use your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service. A local MCP server lets external AI agents work with your Astah models. Conventional reverse engineering of Java, C#, and C++ code is also included. Astah UML runs on Windows, macOS, and Linux with a bundled Java runtime. A free license is available for students, and a 20-day free trial is available. Latest version: 12.0 (released July 15, 2026).Starting Price: $6.99 per month
