About Astah System Safety
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/D-Case assurance cases, ASAM SCDL safety concepts, 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. Safety engineers in automotive, aerospace, railway, and embedded systems use it to build safety cases for standards such as ISO 26262.
AI Chat Copilot and a local MCP server require your own API key from a supported AI service (OpenAI, Claude, Gemini, or an OpenAI-compatible endpoint). SysML models can be exchanged with Cameo Systems Modeler through XMI import and export.
Runs on Windows and macOS. FTA, FMEA, and simulation are not included. A 40-day free trial is available.

SysMLv2 Editor
SysMLv2 Editor is a Visual Studio Code extension from Change Vision, Inc. for writing SysML v2 models in the standard textual notation. Models are saved as plain-text .sysml files in your VS Code workspace.
Features include syntax highlighting, real-time detection of syntax and spelling errors, jump to definition and reference navigation, an outline view for a structural overview, and automatic diagram generation from the text.
SysMLv2 Editor runs on Windows, macOS, and Linux. It is included at no extra cost with a valid Astah SysML, Astah System Safety, or Astah Faculty Site License, and it stays available while that license is valid. A 20-day free trial is available. It is not data-compatible with Astah products, so it does not open SysML v1 models created in Astah SysML.
