About
Astah Professional is an all-in-one modeling tool for software and system design, developed by Change Vision, Inc. It supports UML 2.x, ER diagrams, data flow diagrams (DFD), flowcharts, requirement diagrams, CRUD, and mind maps in a single tool.
Unlike drawing tools, Astah creates models: a change to a model element is reflected in every diagram that uses it, so your diagrams stay 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 Professional is a desktop application for Windows, macOS, and Linux, with a bundled Java runtime, so no separate Java installation is required. A 20-day free trial is available.
Latest version: 12.0 (released July 15, 2026).

About
GoJS is a JavaScript and TypeScript library for building interactive diagrams and graphs. From simple flowcharts and org charts to highly-specific industrial diagrams, SCADA and BPMN diagrams, medical diagrams such as genograms and outbreak modeling diagrams, and more. GoJS makes constructing graphs of complex nodes, links, and groups easy with customizable templates and layouts. GoJS offers advanced features for user interactivity such as drag-and-drop, copy-and-paste, in-place text editing, tooltips, context menus, automatic layouts, templates, data binding and models, transactional state and undo management, palettes, overviews, event handlers, commands, extensible tools for custom operations, and customizable animations. We maintain hundreds of sample diagrams, detailing different examples of interactivity, templates, and user logic for you to start from. We offer free developer-to-developer support during evaluation.
