The VAST Platform is a comprehensive integrated development environment (IDE) that works with a Smalltalk language runtime. Because it's Smalltalk-based, the IDE and the runtime are essentially a development 'image' that's executed by a virtual machine (VM).
First released as IBM® VisualAge® Smalltalk in 1993, the VAST Platform has built upon this original foundation starting in 2005 and has continued to grow in power and flexibility through ongoing research and development.
VAST has evolved beyond what the original VisualAge developers could have foreseen, and allows developers to quickly iterate new ideas with proven Smalltalk-based live programming methodologies and deploy to a variety of desktop, cloud, Internet of Things (IoT), and on-premise server hardware.
