List of language developers

A language developer is a company or individual that develops and distributes a programming language. This includes vendors, companies that sell an APL implementation, as well as organizations and individuals that develop free implementations.

Not all developers have dedicated pages as they may not have significant involvement in the APL world. This is particularly true of early APL vendors, since in the mainframe era APL implementations were written in machine code for a particular architecture. Many hardware vendors implemented their own version of a dialect like APL.SV but did not contribute significantly to APL design.
