Streamline Complex Interaction Modeling

Astah Professional by Change Vision is a software modeling environment for designing and documenting systems. It supports UML diagrams, entity relationship diagrams, data flow diagrams, flowcharts, requirement diagrams, and mind maps, helping developers communicate software structures, interactions, and processes within a single workspace.

Improved sequence diagram editing and display helps developers maintain complex interaction models with less manual adjustment. Automatic layout now supports combined fragments, making it easier to organize structured interactions, while improved rendering performance makes changes to the stacking order of diagram elements more responsive. Corrections to message reconnection, execution specification positioning, and lifeline movement also help preserve diagram layout during editing. Together, these improvements simplify the process of refining sequence diagrams and communicating system behavior.

Astah Professional is licensed through perpetual and annual subscription options, with organizational and academic licenses also available. Perpetual licenses include one year of support and upgrades, with optional support renewal. See our Astah Professional licensing page for full details.
