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

The SysMLv2 Editor is an extension for Visual Studio Code that allows users to create SysML v2 models using a textual format, developed by Change Vision, Inc. These models are saved as standard .sysml files, enabling them to be managed in Git repositories, compared in pull requests, and evaluated alongside other source code components. Among its features are syntax highlighting, real-time validation according to the SysML v2 grammar, the ability to navigate to definitions, an outline view, and the capability to generate diagrams for analyzing both structure and behavior. While diagrams are provided in a read-only format, allowing for text-based editing, Change Vision also offers an early access version of the SysMLv2 Modeler for direct diagram manipulation. The SysMLv2 Editor is compatible with Windows, macOS, and Linux operating systems. Users can access it through an Astah SysML, Astah System Safety, or Astah Faculty Site License without any additional purchases, and a 20-day free trial is also offered. However, it should be noted that the editor does not support the importation of SysML v1 models from Astah SysML, ensuring a clear distinction between different SysML versions. This focus on SysML v2 could enhance users' experience by providing improved functionalities and a more modern approach to modeling.
