## What it is
Chicory is a WebAssembly runtime written in pure Java that runs Wasm modules on any JVM without native dependencies or JNI. It includes a parser, interpreter, and JIT compiler, with WASI support and a sandboxed execution model.

## Use cases
- run webassembly modules inside a java application
- execute wasm plugins in a jvm environment without native libraries
- embed a wasm runtime in a maven or gradle project
- run wasm on any platform the jvm supports
- sandbox untrusted wasm code with jvm security guarantees
- call exported wasm functions from java code

## When to choose
- you need to run Wasm in a Java application without shipping native binaries for multiple architectures
- you want JVM-level safety, observability, and tooling when executing Wasm
- you need a pure-Java, zero-dependency Wasm runtime

## When to avoid
- you need maximum Wasm execution performance from a mature native runtime like Wasmtime or Wasmer
- your project is not on the JVM
- you need advanced Wasm features or extensions not yet supported by Chicory

## Facets
- artifact type: library
- maturity: active
- function: interpreter, compiler
- domain: -
- platform: jvm, cross-platform
- tags: webassembly-runtime, pure-java, wasi, sandboxing, zero-native-dependencies, webassembly, jvm, runtime
