Description
Keep your preferred diagram views and UML tools easily accessible to enhance your efficiency and productivity. The UML diagrams you generate with UModel offer complete customization in aspects such as size, position, color, typeface attributes, and line styles. Use case diagrams are frequently treated as distinct from other software architecture diagrams, as they effectively capture project requirements and help outline the scope of an application being developed. It is uncommon for a project to employ every type of UML diagram, as software modeling encourages a variety of preferences and styles, with different tasks necessitating various diagram formats. No matter which diagrams you choose to create, UModel delivers an unparalleled visual interface and user-friendly features, making UML modeling both simple and enjoyable. Each specific diagram type is equipped with its own dedicated toolbar, ensuring that the workspace remains uncluttered by unrelated icons. Additionally, you have the option to toggle toolbar text labels on or off and can choose to display or conceal any toolbar as needed, giving you greater control over your workspace. This flexibility allows you to focus on your modeling tasks without distraction.
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.
