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

Astah System Safety is a comprehensive tool designed for model-based safety analysis in critical systems, created by Change Vision, Inc. This innovative software integrates SysML modeling with STAMP/STPA hazard assessments, GSN (Goal Structuring Notation) assurance cases, ASAM SCDL, and UAF, all within a single platform. By linking safety analyses directly to the system model, it ensures that control structures, hazards, and safety arguments remain traceable to both requirements and system architecture. This tool is particularly valuable for safety engineers working in sectors such as automotive, aerospace, and embedded systems, facilitating safety-case development in compliance with standards like ISO 26262. Additionally, the AI Chat Copilot feature utilizes your own API key for various services, including OpenAI and Azure OpenAI, and connects to a local MCP server to integrate external AI agents with your models. Models can be easily shared using XMI format and with Cameo Systems Modeler for enhanced collaboration. Astah System Safety is compatible with both Windows and macOS platforms, although it does not include Fault Tree Analysis (FTA) or Failure Mode and Effects Analysis (FMEA). A free trial period lasting 40 days allows potential users to explore its capabilities before committing to a purchase. Overall, this tool represents a significant advancement in ensuring the safety of complex systems.
