Jikes RVM (Research Virtual Machine) provides a flexible open testbed to prototype virtual machine technologies and experiment with a large variety of design alternatives. Jikes RVM runs on many platforms and advances the state-of-the-art of virtual machine technologies for dynamic compilation, adaptive optimization, garbage collection, thread scheduling, and synchronization. It is self-hosted, i.e. its Java code runs on itself without requiring a second virtual machine. Most other virtual machines for the Java platform are written in native code (typically C or C++). A Java implementation provides ease of portability and a seamless integration of virtual machine and application resources such as objects, threads, and operating-system interfaces.

Jato is an implementation of the Java virtual machine. It includes a VM and a JIT compiler for the x86 machine architecture and supports the JNI API. Jato uses Boehm GC as its garbage collector and relies on GNU Classpath to provide essential Java APIs.

xNBD is yet another NBD (Network Block Device) server program, which is fully compatible with the NBD client driver in the Linux kernel. In comparison with the original NBD server, it provides possibly better I/O performance by using mmap(), concurrent access from multiple clients, distributed Copy-on-Write disk, and live storage migration for virtual machines.

The diskegrator is a utility for integrating directory disk images and a bootloader into a bootable image. It was originally intended to build virtual machines, but the target disk images can reside on hard disks, disk partitions, block device targets, or files via loopback.

Shannon is a general purpose stream-oriented programming language; it is concise and yet feature rich. Streams, FIFOs, and Unix shell-style pipes are first-class concepts in the language. You can connect functions and FIFOs within your program similar to the way you connect processes with pipes in the Unix shell. These constructs in Shannon, however, are highly efficient as no true multitasking is involved, and at the same time they allow you to write more concise and readable code for chained data processing. State is a special type of function that returns a reference to its own local data and any nested functions it may have. In effect, states implement classes in terms of OOP, and yet classes per se aren't part of the language. A special type of modules marked as "persistent" is an effective replacement for databases and SQL. This allows you to access persistent shared data using native Shannon constructs, eliminating the need for an extra query language. Intuitive and minimalist syntax and semantics are used. Particularly, "minimalist semantics" means less things to remember and more possibilities. Shannon is statically-typed, although it provides dynamic typing facilities as well.

The Objeck computer language is an object-oriented computing language with functional features that has ties with Java, C#, and Pascal. In this language, all data types are treated as objects. The language consists of a compiler and VM with an accompanying memory management and JIT compiler.

The Supernova programming language is a modern scripting language and the first one that presents the concept of programming with direct fiction description using a clear subset of pure human language. It is easy for users with no programming experience. It is not sensitive to case, spaces, tabs, or line breaks. It support GUI programming. The source code can be written in a mixture of Arabic and English. It lets you distribute directly executable application files. It lets you use the Windows API and call DLL functions. It includes libraries for sound playing, sound recording, and movie playing. It includes commands for text processing, date and time processing, multi-dimension arrays, and file I/O. Its documentation includes many samples and tests.

pyvm3 is a hobby project that's based on a compact virtual machine that can run Python bytecode and supports classic Python and whitespaceless Python frontends. On top of this there are implementations of various applications like a Web browser, PDF viewer, font rasterizer, SSH, PGP, a windowing environment on linuxfb, a video/MP3 player, and more.

MyJIT is a small modular library for dynamic code generation based on a simple register-based VM. The design of the VM is very similar to RISC processors and GNU lightning. The library is an ideal tool for creating more sophisticated JIT compilers.

Embeddable JVM is a JVM for embedded systems with no OS. Class files can be executed directly from an SD card. It has small memory consumption (512k is enough). Only the FAT16 filesystem is supported for now. It has been tested on LPC2478 and LPC2939 boards.
