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
Cameo Systems Modeler ™ is an industry leading cross-platform collaborative Model-Based Systems Engineering (MBSE) environment, which provides smart, robust, and intuitive tools to define, track, and visualize all aspects of systems in the most standard-compliant SysML models and diagrams. The environment enables systems engineers to: Run engineering analysis for design decisions evaluation and requirements verification, continuously check model consistency and track design progress with metrics. System models can be managed in remote repositories, stored as standard XMI files, or published to documents, images, and web views to address different stakeholder concerns.
