  Squeak is an open-source Smalltalk programming system available for all major platforms. It features the Morphic framework, which promotes low effort graphical, interactive application development and maintenance. Many projects have been successfully created with Squeak in a wide range of domains such as education, multimedia, gaming, research, and commerce. Squeak is fast, flexible and free.
  
  It''s Smalltalk!!!!
  Everything is an object. Objects collaborate by sending messages to achieve the desired application behavior. The Smalltalk programming language has a concise syntax and simple execution semantics. The Smalltalk system is implemented in itself: Compiler, debugger, programming tools, and so on are all Smalltalk code the user can read and modify. Novice programmers can get started easily and experts can engineer elegant solutions at large.
  
  Morphic UI Framework
  All graphical objects are tangible and interactively changeable. This promotes short feedback loops and low-effort application development. Morphic thus leverages the live programming experience of traditional Smalltalk environments from a mainly text-focused domain to a graphical one.
  
  Powerful Tooling
  The dynamic Squeak environment provides a variety of tools for browsing, writing, executing, and versioning Smalltalk code. Multiple debugging sessions can be served concurrently. Thanks to Morphic, tool customization can be achieved with reasonable effort.
  
  Fast Virtual Machine
+ The standard VM for Squeak, Cog Spur, has the most advanced object representation yet devised for Smalltalk. Spur has direct pointers, a compact object header, and efficiently implements become (Smalltalk''s object mutation primitive) via lazy forwarding. Spur provides pinning, and a segmented heap, releasing memory back to the OS after global garbage collection. Cog Spur''s JIT combines context-to-stack mapping, aggressive in-line message caching, a register based calling convention, and Spur''s object representation to provide the fastest production Smalltalk VM.  Cog Spur is developed in Smalltalk, in a uniquely productive VM development environment. There are other important Squeak VMs, SqueakJS that runs in web browsers, and the research meta-tracing JIT TruffleSqueak, exploring the Truffle/Graal framework.

  Web Development
  With frameworks like Seaside and AIDA, Squeak can be a web server. It provides a layered set of abstractions over HTTP and HTML that let you build highly interactive web applications quickly, reusably, and maintainably.
  
  Multi-Platform Support
  Squeak supports Windows, Linux (X86, X64 and ARM), and macOS and is preinstalled on C.H.I.P., Raspberry Pi, and OLPC XO.!!
