Fast, safe, complete libvips bindings for image processing in Java / JVM projects

Gradle plugin that generates Java bindings from native library headers using Jextract

High-performance networking built on Linux io_uring for true async I/O with zero-copy buffer management and kernel bypass capabilities.

PCRE2 bindings for Java — drop-in java.util.regex replacement with JIT compilation and ReDoS protection

MYRA Codec is a high-performance binary serialization library with a schema-first design. It supports full schema evolution, union types, and zero-copy encoding/decoding paths for maximum throughput.

Roray FFM Utils is the foundation layer of the MVP.Express stack. It provides high-level, type-safe abstractions over JDK’s Foreign Function & Memory (FFM) API, enabling efficient off-heap memory management without the complexity of raw pointer manipulation.

Java bindings for the Wasmtime WebAssembly runtime — dual JNI (Java 8+) and Panama FFM (Java 23+) backends, with Component Model and WASI support.

A JavaFX GUI wrapper for the jextract tool

Java FFM (Foreign Function & Memory) bindings for zstd — hermetic zig build, dictionary support, zero-copy MemorySegment API

Vortex columnar format, in pure Java (zero-copy, FFM, no JNI, no Unsafe)

Local LLM for the JVM — llama.cpp via Project Panama FFM (no JNI). OpenAI-compatible Spring Boot starter + Spring AI adapter + CLI. Streaming, tool calling, real token usage.

Example of OpenGL binding using Java25, FFM and jextract

MIRROR ONLY - High-level Java bindings for libopus, built on top of the JDK 25 Panama Foreign Function & Memory (FFM) API.

MIRROR ONLY - Encode and decode VP8/VP9 video in Java — no JNI, no native compilation. Drop-in libvpx bindings for Java 25+ with a simple byte[] API and an optional zero-copy MemorySegment path.

Example of direct usage of opengl and glfw (without JNI) with java 22 Foreign Function & Memory API (FFM API)

JNI Header Wrapper a lightwight alternative to JNA or JNR (V 4.0.0-SNAPSHOT in branch FFM uses JEP 454: Foreign Function & Memory API)

Windows platform API bindings, utilities and penetration testing framework

Java (FFM) API for Zstandard (zstd)

High-performance off-heap cache for Java 25+ using the Foreign Function & Memory API. No Unsafe. Built for large, low-latency in-process caches.

Gradle plugin that downloads jextract and generates Java FFM bindings, with optional bundled library loading.
