About the company
Astah was originally created by Japanese company ChangeVision in 2006 as a UML modeling tool. The software has grown to include six different tools, each designed to meet different diagramming needs, including UML, SysML, GSN, and more.
Today, the company’s vision is guided by Kenji Hiranabe and remains committed to simplicity, quality, and community.
Astah is so much more than just a diagramming software. It is part of a development methodology that values strategic planning and communication across teams. With our blog, we hope to inspire the software engineering industry to follow these best practices, and we continue to provide excellent documentation for our simple but powerful tools!Explore the blog
