What is Astah UML?

Astah UML is a desktop UML 2.x modeling application from Change Vision, Inc. It is designed for development teams, universities, and individual engineers who need standard UML diagrams without the complexity of a full systems-engineering suite. Because designs are stored as models, an update made in one place carries through to every related diagram, which keeps design documentation consistent as a project grows. Version 12.0, released in July 2026, brings AI into UML modeling. 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. Local MCP server integration lets AI agents connect to Astah models. Plans start at $6.99 per month. A free license is available for students, and a 20-day free trial is offered. Astah UML runs on Windows, macOS, and Linux without a separate Java installation.
