JUDE development was started by Kenji Hiranabe, CEO of Change Vision, Inc., in 1996.[citation needed]

JUDE was provided as a free software in 1999. Five years later JUDE started selling in the Japanese market. This decision came about because some UML modeling tools existed overseas but they were a bit high priced; and the company would get feedback from Japanese users and could evolve more if JUDE was released on the market.[4]

The number of JUDE users was 120,000 as of October 30, 2006. In September 2009, JUDE was renamed to Astah after receiving concerns from German users who pointed out the product name was similar to the German word Jude, which refers to a male Jew.[5]
