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

SysMLv2 Editor is a Visual Studio Code extension for writing SysML v2 models in the textual notation, developed by Change Vision, Inc. Models are plain .sysml files, so they can be tracked in Git, compared in pull requests, and reviewed alongside source code. Features include syntax highlighting, real-time validation against the SysML v2 grammar, navigate to definition, an outline view, and diagram generation for reviewing structure and behavior. Diagrams are read-only; editing happens in the text. For editing directly on diagrams, Change Vision offers SysMLv2 Modeler (early access). SysMLv2 Editor runs on Windows, macOS, and Linux. It is included with an Astah SysML, Astah System Safety, or Astah Faculty Site License, with no separate purchase, and a 20-day free trial is available. It does not import SysML v1 models from Astah SysML.
