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
Enhance your drawing speed with advanced auto-snap features and intelligent tools designed for efficiency. Seamlessly export your work in high-quality PDF and SVG formats without any subscription fees or monthly charges. The auto-snap feature ensures objects align perfectly for precise outcomes, while the ability to natively embed LaTeX equations directly into diagrams adds a layer of sophistication. With smart tools at your disposal, routine tasks become simpler, allowing you to focus on creativity. Utilize powerful Bezier curves and boolean path operations to craft intricate illustrations effortlessly. Vexlio empowers you to generate high-quality PDF diagrams by exporting your artwork with ease. Similar to SVGs, PDFs maintain clarity and smoothness regardless of scale, making it possible to feature compact diagrams in a paper's margin or a large design as a centerpiece for a poster. Furthermore, Vexlio’s adaptable export system intelligently crops your PDF to fit the precise dimensions of your drawing, eliminating any additional effort on your part. You also have the option to export only selected objects, streamlining the process even more. With these features, your productivity and creative potential can thrive like never before.
