Overview AI

Squeak/Smalltalk is a modern, open-source implementation of the Smalltalk language that treats everything in the environment as an object. The system is entirely self-hosted, meaning the compiler, debugger, and user interface tools are written in Smalltalk and can be modified at runtime. It features the unique Morphic framework, allowing developers to create graphical interfaces through direct manipulation of objects. This resource is intended for developers, educators, and researchers looking for an expressive, interactive, and highly dynamic environment.
