About

Astah SysML is a SysML v1 modeling tool for systems engineering and model-based systems engineering (MBSE), developed by Change Vision, Inc. It supports block definition, internal block, requirement, parametric, use case, state machine, activity, and sequence diagrams, plus requirement tables and mind maps. Designs are stored as models, so a change to a block or requirement is reflected in every diagram that uses it. Profiles, XMI import/export, and data exchange with Cameo Systems Modeler are supported. 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 lets external AI agents work with your models. Astah SysML runs on Windows and macOS. Simulation is not included. A 20-day free trial is available. For SysML v2, Change Vision offers separate products that run as Visual Studio Code extensions: SysMLv2 Editor and SysMLv2 Modeler (early access).

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.
