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.
The visual evolution of VAST
"Due to technical maturity and a purely object-oriented paradigm, our VAST-based systems are ahead of newer system technologies in terms of stability and performance."
Product Owner, AXA Switzerland
"The dynamic nature of Smalltalk plus the rich and stable toolset of the VAST Platform — paired with the pace of innovation at Instantiations — puts everything in your hands that's needed to build and maintain sustainable systems."
Proven by the Enterprise. Available to Everyone.
For more than 15 years, VAST has been setting the standard for software stability and maintainability for businesses of all sizes.
Stability with Innovation
Maintaining stability with software is easy if it never changes. While we know stability is essential, continued innovation and keeping pace with ever-evolving standards cannot be overlooked.
Speed plus Efficiency
With low memory usage, and fast just-in-time (JIT) compilation, Instantiations' VAST virtual machine (VM) has been optimized for decades at this point, and is now much faster than IBM's original VM.
VAST includes the latest cryptographic libraries, like OpenSSL 1.1, and other advanced frameworks to help developers keep their software secure and meeting current standards.
The VAST Platform is available for Windows® and various Linux® distros, and on both 32 and 64-bit Intel®/AMD®-based hardware.
Coming in Q3 2021: ARM® 32 and 64-bit support!
Code Once. Deploy Anywhere.
Develop your software from a single development machine and easily deploy to on-premise servers, cloud services, and IoT devices with deployment image sizes that can be less than 1MB. VAST works well with Docker®, Kubernetes®, and OpenShift® containers too.
VAST is powered by Smalltalk
Smalltalk was ahead of its time, and its characteristics still prove to be best-in-class with dynamic languages.
Powerful, Simple Syntax
There are only 6 reserved keywords in the VAST Platform (Smalltalk) and the language itself is one of the most human-readable programming languages. VAST works through message sends between objects and those messages are implemented as methods.
Literally everything in VAST is an object. Use a consistent and powerful model for building programs without having to switch between objects and non-objects. Our virtual machine does a tremendous amount of optimizations to improve the speed of this approach.
Efficiency with Snapshots
VAST uses development images that are run by a virtual machine. It's like having your own operating system that you can save, rollback, and distribute all from the same place. Snapshots enable resuming work exactly where you left off at a later point...even on a different computer.
Live & Remote Debugging
VAST is able to run your program, debug it, and modify it while it's running in a live environment. Fine-tune the behavior on-the-fly without needing to recompile or stop execution. Stack traces can be snapshotted to resume debugging later, even from remote locations.
Smalltalk programmers have touted exceptional productivity in the language for years, and a recent study has indicated that Smalltalk can be more productive than languages like Java, Python, Ruby, and C#.
VAST is not just another IDE and language runtime. Included within VAST are hundreds of libraries and tools to help improve stability, productivity, and security within your application.
"I have built significant software systems in several different languages. And so, I can say with experience and conviction that Smalltalk is the most productive development language I have ever used."

Hundreds of Features, Frameworks, Libraries
All are included in the platform to improve stability, productivity, and security within your application.
