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.
Description
Flowcharts created in DrakonHub adhere to ergonomic principles established by the aerospace sector, which effectively eliminates visual clutter from diagrams. This clarity emphasizes the primary path using a skewer, while logical segments are delineated through the silhouette technique. Implicit relationships are highlighted via the concept of common fate, adding organization to mind maps. It is crucial to ensure that the diagram's structure is immediately recognizable, as a clear framework allows readers to understand how each element interacts with its parent, siblings, and offspring. Prior to coding, it's beneficial to sketch the program, revising the sketch throughout the development process. This visual representation provides essential clarity that can significantly enhance productivity. After six months, this initial sketch will serve as a valuable reference for recalling the program's complexities and nuances. Diagrams serve as an effective means of documenting project knowledge succinctly, and it is important to retain ownership of this information rather than allowing developers to obscure it within the source code. Ultimately, maintaining clarity in documentation will facilitate better communication among team members.
