Tiny C compiler, programmed in C with compiler/linker/assembler included. VERY fast and mainly usable as a library. WIN32 port of the http://tinycc.org version. Compiles code to memory currently, perhaps disk soon. Go to the homepage for more info.

JWasm is a Masm-compatible assembler. It supports 16-, 32- and 64-bit code, instructions up to AVX and various output formats. It's written in C.

An open source COBOL compiler for the PC x86-32 platform. Generates GNU assembler and requires GCC to produce a binary. Supports Linux, BSD and MinGW 32 bit platforms.

Software Development Kit for the Nintendo(tm) Gameboy Advance(tm) based on GCC.

DOS/32 Advanced DOS Extender is a drop-in replacement for the DOS/4GW DOS Extender and compatibles. Being fast, small and flexible DOS/32A can be used in many environments, from embedded systems to DOS emulators, by both developers and end users alike.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

colorForth is, in Chuck Moore's own words: "A dialect of Forth that uses color to replace punctuation. Includes its own operating system. Produces extremely compact programs. Instant compile from pre-parsed source."

TempleOS is a 64-bit kernel with compiler, graphics library and tools. It is not a Unix. It was made from scratch.

Z88DK is a complete Z80 / Z180 development kit that includes C compiler, assembler, linker, a tool for generating executables in a number of formats, and miscellaneous other tools. Over 80 machines are directly supported out of the box including standalone Z80 and Z180 embedded systems. Z88DK's extensive assembly language libraries give it significant performance advantages over other Z80 C Compilers. Building software for standalone or generic Z80 systems: https://www.z88dk.org/wiki/doku.php?id=libnew:target_embedded Visit us at github for the current version with bugfixes and new features: https://github.com/z88dk/z88dk

ImpLib SDK combines free programming tools for authoring custom import libraries for Windows DLL (32 and 64 bit). The SDK supports advanced features, like cdecl2stdcall conversion, importing by ordinal, removing original thunk, storing symbols from different DLL files in a single import library. The ImpLib SDK is also useful to overcome any legal restrictions when redistributing the import libraries for certain DLL files, like the Microsoft® C++ runtime. The import libraries for the CRT or STL are part of the Windows SDK. Even though the SDK is available for free, redistributing these files is not allowed according to the current license agreements. An alternative is to generate these import libraries using the ImpLib SDK, as it doesn't restrict redistribution. The ImpLib SDK is free even for commercial use and redistribution of any kind, as long as all copyrights are preserved.
