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

Malfunction backend for Idris with a FFI to OCaml

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

Linux open by handle based VFS implementation for nfs4j

A modern, JIT-powered, and dependency-free Foreign Function Interface (FFI) library and type introspection engine for C. Dynamically call native functions and create secure callbacks using simple, human-readable signatures. Ideal for language bindings, plugins, and dynamic library interactions.
