What is Astah SysML?

Astah SysML is a desktop SysML v1 modeling application from Change Vision, Inc. for organizations adopting model-based systems engineering (MBSE). It gives engineering teams the core SysML diagrams, including requirement, block, parametric, and behavior diagrams, in a tool that new users can learn quickly.

Because designs are stored as models, an update made in one place carries through to every related diagram, which keeps system documentation consistent as a project evolves. Existing models can be exchanged through XMI and with Cameo Systems Modeler.

Version 11.0 includes AI Chat Copilot, which runs on your organization's own API key for OpenAI, Azure OpenAI, Claude, or Gemini, or for an OpenAI-compatible service, and local MCP server integration for connecting AI agents.

Licensing is available as a 1-year license ($140) or a 1-year floating license ($270). Astah SysML runs on Windows and macOS, and a 20-day free trial is available.
