TL;DR
Endive is a new WebAssembly runtime built for the JVM, offering native-like performance without native dependencies. It is designed to improve safety and ease of use for Java developers integrating WebAssembly.
Endive, a JVM-native WebAssembly runtime, has been announced as an open-source project designed to run WebAssembly programs without native dependencies or JNI, making it easier for Java developers to embed Wasm in their applications.
Endive is a fork of Chicory by Dylibso, Inc., and is developed to address the limitations of existing WebAssembly runtimes that rely on native code, such as V8 or Wasmtime. Unlike these, Endive runs entirely within the JVM, eliminating distribution and runtime friction associated with native libraries. It supports core WebAssembly specifications and aims to provide a safe, simple, and idiomatic way to execute Wasm modules in Java environments.
The project emphasizes safety, simplicity, and compatibility, targeting Java developers who need to embed WebAssembly without sacrificing JVM security guarantees. Endive is built with a modular architecture, supporting features like SIMD, tail calls, exception handling, and multithreading, with ongoing development to support performance enhancements and advanced features.
Why It Matters
This development matters because it could significantly streamline the integration of WebAssembly into Java applications, reducing complexity and increasing portability. By avoiding native dependencies, Endive offers a more secure and consistent environment, especially for enterprise and cloud-native Java applications that require strict security and deployment controls. It also aims to become the default runtime for WebAssembly on the JVM, potentially influencing future standards and adoption.

Background
WebAssembly has gained popularity as a portable, secure binary format for web and server applications. Existing runtimes like V8, Wasmtime, and Wasmer are widely used but depend on native code, complicating deployment in Java environments. Chicory, introduced in September 2023, was an early effort to create a pure JVM runtime, and Endive builds on this foundation, aiming for broader adoption and feature completeness. The project is part of a larger trend toward zero-dependency runtimes that prioritize safety and simplicity in enterprise settings.
