## What it is
Gambit is a complete, portable, and efficient implementation of the Scheme programming language, including an interpreter (gsi) and an optimizing compiler (gsc) that can target C, JavaScript, and Python. It offers Erlang-like lightweight concurrency and runs on a wide range of platforms from servers to embedded devices and web browsers.

## Use cases
- run and develop Scheme programs interactively
- compile Scheme to fast native code via C
- build concurrent applications with lightweight threads
- run Scheme in the browser by compiling to JavaScript
- embed a Scheme interpreter in C applications
- learn or teach functional programming with Scheme

## When to choose
- you need a fast, mature Scheme implementation with a good compiler
- you want Erlang-style concurrency with Scheme syntax
- you need extreme portability across platforms and targets
- you want an interactive interpreter plus optimizing compiler in one system

## When to avoid
- you need a mainstream language with a large ecosystem and hiring pool
- you require extensive third-party libraries beyond Scheme SRFIs
- you need first-class IDE tooling and package management out of the box

## Facets
- artifact type: cli-tool
- maturity: stable
- function: interpreter, compiler, programming-language, concurrency
- domain: programming-languages, compilers, developer-tools
- platform: windows, cross-platform, cli, browser, cpp
- tags: scheme, r7rs, lisp, language-implementation, lightweight-threads, linux, macos
