SmalltalkSystems

SmalltalkSystems is a software company and platform developer focused on the Smalltalk programming language and its ecosystem. The company builds tools, runtimes, and enterprise applications designed to support rapid development, live programming, and maintainable codebases using Smalltalk. It serves customers in education, research, and industry and offers both commercial and educational editions of its products.

Founded in the late 1990s by a group of Smalltalk practitioners and educators, SmalltalkSystems aimed to standardize and improve development tooling for Smalltalk environments. It released its flagship Smalltalk Platform Suite in the early 2000s, combining an integrated development environment, a portable virtual machine, and a comprehensive standard library. Since then the company has expanded to provide cloud-ready deployment options, interoperability adapters, and professional training services.

Key products include the Smalltalk Platform Suite (SPS), the Smalltalk Runtime Engine, and a Smalltalk Web Framework. SPS provides features such as live coding, advanced debugging, and cross-platform graphical user interface toolkits that run on major desktop operating systems. The educational edition is designed for classroom use and curriculum development in computer science programs.

Technology and approach emphasize compatibility with existing Smalltalk dialects, open-source collaboration, and interoperability with modern software stacks through RESTful interfaces and web services. SmalltalkSystems maintains documentation and community resources to support adoption by developers, educators, and researchers.
