Implementations

Native Compilers

• Chez: R6RS, official installer also for Windows, considered one of the fastest scheme implementations.
• Ikarus R6RS
• MIT/GNU Scheme: R7RS

Uses another Scheme as backend

• Gerbil: R7RS, compiles to C, based on Gambit, extends gambit with better macro and module systems.
• Racket: R6RS, beginner friendly, full Windows support, optional typing, essentially a superset of scheme, tons of libraries, moving/moved to a Chez Scheme backend.

Transpilers to C

• Chicken: R5RS and R7RS, beginner friendly, exceptional community, unique implementation of GC.
• Cyclone: R7RS, experimental extension of Chicken-style GC with native thread support.
• Gambit: R5RS, official installers also for macOS, iOS, Windows, considered quite fast.
• Bigloo: R5RS, can also compile to Java-Virtual-Machine (JVM) classes, limited optional typing.

Bytecode VM's and JVM/CLR

• Chibi: R7RS
• Gauche: R7RS, compiles to standalone executable, official installers also for Windows, Docker.
• GNU Guile: R6RS, getting JIT executable support soon, beginner friendly, officially supported by GNU, scripting language for many pieces of GNU software.
• IronScheme: R6RS, based on Common-Language-Runtime (CLR).
• Kawa: R7RS, based on JVM, compile to JVM classes, limited optional typing.

Javascript Interpreter

• BiwaScheme

Unmaintained

• Larceny: R6RS and R7RS, generate native code, official installers also for macOS, Windows.
• Scheme48: classic, unmaintained but useful.
• Scsh: classic, unmaintained but useful.
• Ypsilon: classic, unmaintained but useful.

Package Managers

• Akku: Implementation agnostic R6RS and R7RS packages.
• GNU Guix: Functional package manager and operating system distribution for GNU sytem.
• Snow: Portable R7RS libraries.
• Racket: Racket-specific packages.

Read, Learn, Teach

• Bibliography of Scheme-related Research
• Structure and Interpretation of Computer Programs: classic computer science textbook from MIT
• The Scheme Programming Language 4th Edition: Written by Kent Dybvig of Chez Scheme fame.

Editor and IDEs

• Geiser: most comprehensive Emacs support for many Scheme implementations (MELPA)

Applications

• SIAG: Scheme In A Grid: old Scheme-scriptable spreadsheet with built-in web server

Web Development

• chibi html-parser: lenient HTML parser (R7RS; Docs; Akku, Snow)

Languages and computation

• Nanopass Framework: a DSL for factoring compilers into many small passes and IRs

Numerical code

• Harlan: a Scheme-based programming language for GPU computing

Foreign Function Interface

• r6rs-pffi - portable foreign-function interface for several implementations (R6RS; Home & Docs; Akku)
