Description

Astah Professional helps software teams design systems visually, before and while they write code. One application covers UML 2.x, entity-relationship diagrams, data flow diagrams, flowcharts, requirement diagrams, CRUD matrices, and mind maps, so architects and developers do not have to switch tools between notations. Diagrams in Astah are views of a shared model. When you rename a class or change a relationship, every diagram that contains it is updated automatically. For AI-assisted work, Astah Professional 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 work with your Astah models. Conventional reverse engineering of Java, C#, and C++ code works without an AI service. The tool runs locally on Windows, macOS, and Linux and ships with its own Java runtime. Developer: Change Vision, Inc. Current version: 12.0 (July 2026). A 20-day free trial is available.
