The goal of this category is to be the most comprehensive list of Forth implementations and links on the Internet. Forth is a programming language with a lot of implementations; you might say it is implementation rich; it may have more implementations than any other language. This is a strength and a weakness; it has positive and negative aspects, depending on your application. Many other languages are standardized, or complex and large, and when users want a new feature or change, they write an extension. Forth is less standardized and very compact, and when users want a new feature or change, they write an implementation. Forth philosophy is: If you can't find what you want in an extant Forth, write your own. Flexibility is the key virtue and goal.
The friendly Forth compiler/interpreter: detects virtually every error and reports what and where they occur, but is still fast and compact. Uses only signed 32 bit numbers. DOS, Windows, Unix.
Forth-based, data-entry, data-base, screen-handling language. Automatically handles routine housekeeping that usually accounts for 90% of interactive application code. All Abundance programs can jaunt (run backward in time).

Originally started as a Forth implementation for Intel microprocessors, It now comprises ISO-Forths in fig-Forth tradition (one assembler source file) for quite some targets. Targets are 16,32 and 64 bit Intel on MS-DOS, MS-windows and Linux, and as stand-alone. Non-Intel targets include the Motorola 6809, and the Renesas M16C (embedded) and the DEC Alpha (Linux).

Forth for i586-PC-Linux: kernel shared library, realtime, multitasking, executable code compiling Forth system. Written in Intel style assembly language (NASM); designed not for portability, but for efficiency. Open source.
A 32-bit ISO-Forth for Linux in fig tradition is presented. It is based on an assembler in only one file, so no c-code is present nor are any c-libraries called. Binary file works on all Linux versions since 1.2. GPL.
Runs on Linux OS, similar to eForth. Goals: simple, easy to understand first, speed and elegance later; able to call functions (procedures) in dynamic linked library (.so files). Download, development forum.
Written in Java, so its interpreter can be embedded in a WWW HTML page and launched as an applet, to show that almost any programming language can be implemented in Java and not suffer unacceptable performance losses; documentation, downloads as a Forth Java applet.
