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.
