Description
Astah Professional helps software teams design systems visually, before and while they write code. One application covers UML 2.x, entity-relationship diagrams, data flow diagrams, flowcharts, requirement diagrams, CRUD matrices, and mind maps, so architects and developers do not have to switch tools between notations.
Diagrams in Astah are views of a shared model. When you rename a class or change a relationship, every diagram that contains it is updated automatically.
For AI-assisted work, Astah Professional 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 work with your Astah models. Conventional reverse engineering of Java, C#, and C++ code works without an AI service.
The tool runs locally on Windows, macOS, and Linux and ships with its own Java runtime. Developer: Change Vision, Inc. Current version: 12.0 (July 2026). A 20-day free trial is available.
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.
