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.
