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
Systems engineering projects are much more likely to succeed if every stakeholder can easily contribute to the process, but most people don’t have the training needed to use traditional SE tools, or work with the complex modeling languages found in SE practices. MapleMBSE makes broad engagement possible with Excel-based, task-specific interfaces for each activity in your SE project. By giving all stakeholders access to the process through a live, two-way connection to the model of your system, you can ensure that all stakeholders can collaborate through the systems model, allowing them to work faster, avoid errors, and reduce unbudgeted costs. The MapleMBSE interface is simpler to apply, it gives system engineers more flexibility for making model adjustments, and overall it cuts down knowledge-capture errors.
