Lisp / Scheme · 1995Actively developed

A language platform for building languages, teaching and interactive application development.

Procedural · Functional · Object-oriented

Tracked release

Version: 9.3
Artifact: Language / runtime distribution
Published: Date not verified
Source checked: 2026-10-22

Use & ecosystem

Suited for: Web backends, CLI tools / automation, Symbolic / logic programming
Family / tradition: Functional / ML / lazy, Lisp
Maturity: Stable niche
Ecosystem breadth: Focused

A stable distribution and long-lived tools justify Stable niche. Its substantial language-building ecosystem is specialized rather than industry-wide general application coverage.

Industry & practical use

Language design, DSLs, education and developer tools are especially strong fits. Web and GUI libraries also exist, with a smaller adoption base than mainstream application stacks.

Compilers, libraries & tooling

DrRacket, the package system, documentation tools and syntax facilities form an integrated environment. Typed Racket is a separate typed language within the distribution.

Platforms & deployment

General toolchains: Linux, Windows, macOS
Specialized tooling: None catalogued
Native cross-compilation: Restricted / involved

The distribution supports major desktop/server systems. GUI and native package dependencies can constrain deployment.

Cross-building distributions or executables requires platform-specific support; it is not interchangeable with ordinary same-host packaging.

Project health & support

The Racket project has sustained academic and community support. Core continuity is strong, while individual packages have independent maintainers.

History & origin

Racket grew from PLT Scheme, begun in 1995, and adopted the Racket name in 2010. It developed a larger language platform rather than remaining simply another Scheme implementation.

Creators: Matthias Felleisen, Matthew Flatt, PLT group
Origin: 1995 — PLT Scheme project origin; renamed Racket in 2010.

Language features

Typing: Dynamic, Static
Execution: Bytecode VM, JIT
Block structure: Explicit delimiters
Semicolons: Not statement separators
Lexical closures: Yes
Namespaced modules: Yes

Implementation notes

Dynamic describes ordinary Racket; Static refers to Typed Racket. The two should not be confused with one uniformly statically typed language.
