Free Astah Viewer
for Everyone

The free Astah Viewer allows you to use all the powerful features of Astah’s software and still share the files with those who do not have an Astah license. Now, when you ask your clients or colleagues to review your diagrams, just ask them to download the Astah Viewer and open your .asta file! Sharing and reviewing is just that easy!
