Racket is a general-purpose, multi-paradigm programming language. The Racket language is a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation.[9] In addition to the core Racket language, Racket is also used to refer to the family of programming languages[10] and set of tools supporting development on and with Racket.[11] Racket is also used for scripting, computer science education, and research.

The Racket platform provides an implementation of the Racket language (including a runtime system,[12] libraries, and compiler supporting several compilation modes: machine code, machine-independent, interpreted, and JIT) along with the DrRacket integrated development environment (IDE) written in Racket.[13] Racket is used by the ProgramByDesign outreach program, which aims to turn computer science into "an indispensable part of the liberal arts curriculum".[14][15]

The core Racket language is known for its extensive macro system which enables creating embedded and domain-specific languages, language constructs such as classes or modules, and separate dialects of Racket with different semantics.[16][17][18][19]

The platform distribution is free and open-source software distributed under the Apache 2.0 and MIT licenses.[20] Extensions and packages written by the community may be uploaded to Racket's package catalog.
