GNU Prolog is a free implementation (under GPL) of the logic programming language PROLOG. It can compile to native machine code which is extremely fast in execution. Another feature is the included constraint solver.

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.

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.

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.

ELENA is a general-purpose, pure object-oriented language with late binding. It promotes more object-oriented program design, reusable and more standardized code. The package includes compiler, IDE, ELENA libraries and samples

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."

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

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.

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.

Vector Pascal is a language targeted at SIMD multi-core instruction-sets such as the AVX and SSE2 or x86-64-v3. It has a SIMD compiler which supports parallel vector operations, loop unrolling, common sub expression removal etc. It is implemented in Java.

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.
