## What it is
SCI is a small, configurable Clojure and ClojureScript interpreter for evaluating code from user input or building Clojure DSLs. It works on the JVM, GraalVM native images, ClojureScript with advanced compilation, and ClojureDart.

## Use cases
- safely evaluate user-supplied Clojure code
- embed a Clojure DSL in my application
- add a scripting/plugin engine to a Clojure app
- run Clojure in the browser from script tags
- build a Clojure REPL inside a native-image binary

## When to choose
- you need a sandboxed, configurable alternative to eval for Clojure code
- you want to embed a small Clojure dialect in JVM, JavaScript, or GraalVM native projects

## When to avoid
- you need full Clojure semantics and performance rather than a limited interpreter
- you want to interpret a language other than Clojure

## Facets
- artifact type: library
- maturity: active
- function: interpreter, programming-language, plugin-system
- domain: programming-languages, developer-tools, parsers
- platform: jvm, browser, jvm-scripting
- tags: clojure, clojurescript, graalvm, dsl, scripting, safe-eval, nodejs
