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

Ilograph is a cutting-edge interactive diagramming tool aimed at assisting engineers and technical teams in documenting, elucidating, and analyzing intricate systems via dynamic architecture diagrams. Moving beyond conventional static illustrations, Ilograph empowers users to craft interactive, zoomable diagrams that unveil varying levels of detail and viewpoints within a system. Authors can define system resources and their interrelations through a streamlined model-based methodology often known as “diagrams-as-code,” which enhances the structure, consistency, and reusability of documentation. This platform automatically produces layouts and boasts features like autocomplete, integrated icon libraries, and customizable styles that streamline the creation and upkeep of diagrams as systems progress. Each diagram offers multiple viewpoints, illustrating how components interact in various scenarios, including data flows, infrastructure setups, or business workflows. Furthermore, this innovative approach not only fosters better collaboration among team members but also significantly enhances the clarity of complex information.
