Squeak is a modern, open source, full-featured implementation of the powerful Smalltalk programming language and environment.
The Squeak programming language is a dialect of Smalltalk. It is object-oriented, class-based, and reflective.
It was derived directly from Smalltalk-80 by a group at Apple Computer that included some of the original Smalltalk-80 developers. Its development was continued by the same group at Walt Disney Imagineering, where it was intended for use in internal Disney projects. Later on the group moved on to be supported by HP labs, SAP Labs and most recently Y Combinator.
Squeak is a tightly integrated software development environment for live software construction using the object-oriented programming language Smalltalk. It runs on many computers and operating systems. Squeak is free and open source. Squeak has its own unique place in the universe.
