Our flagship products are the April APL compiler and the Seed interactive software environment. April is dedicated to bringing the power of the APL to a new generation of developers through the medium of Common Lisp. And Seed is designed to empower software interfaces in a way that only Lisp can support, by composing interactive elements directly from symbolic expressions.

These two projects are the brightest stars in a constellation of software tools that will address computation, graphics, human/computer interface design and more. Your support helps us to make this software free for everyone to use.

April compiles the APL language into Common Lisp code, allowing you to leverage the power of APL with more data sources and external systems than ever before. April can be used for machine learning, graphics work and more. You can try it out today as simply as evaluating (ql:quickload 'april) in your Common Lisp REPL.
