About
Astah System Safety is a model-based safety analysis tool for safety-critical systems, developed by Change Vision, Inc. It combines SysML modeling with STAMP/STPA hazard analysis, GSN (Goal Structuring Notation) assurance cases, ASAM SCDL, and UAF in one tool.
Safety analyses are linked to the system model, so control structures, hazards, and safety arguments stay traceable to requirements and architecture. It is used by safety engineers in automotive, aerospace, and embedded systems, including safety-case work for standards such as ISO 26262.
AI Chat Copilot works with your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service, and a local MCP server connects external AI agents to your models. Models can be exchanged through XMI and with Cameo Systems Modeler.
Astah System Safety runs on Windows and macOS. FTA and FMEA are not included. A 40-day free trial is available.

About
Astah UML is a UML 2.x diagramming tool for software design, developed by Change Vision, Inc. It covers the core UML diagrams, including class, use case, sequence, activity, state machine, component, and deployment diagrams, plus mind maps.
Astah creates models rather than drawings: when you change a model element, every diagram that uses it is updated, so your design stays consistent.
AI features include AI Chat Copilot and AI-assisted code reverse engineering, which use your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service. A local MCP server lets external AI agents work with your Astah models. Conventional reverse engineering of Java, C#, and C++ code is also included.
Astah UML runs on Windows, macOS, and Linux with a bundled Java runtime. A free license is available for students, and a 20-day free trial is available.
Latest version: 12.0 (released July 15, 2026).
