Welcome, to the home of Thinlisp, a practical dialect of lisp for real world applications. Ship applications with all the benifits of C while getting the power of Lisp as you build your system.

ThinLisp is open source [1] with a BSD style license, i.e. we ask only reasonable credit on the resulting applications.

ThinLisp is the result of a decade of building large [2] systems. ThinLisp is latest in a series [3] of approaches taken to allow us to create practical systems we can ship in Lisp. While all of Common Lisp is available at system build time. the Lisp dialect available in production is a carefully crafted subset of Common Lisp.
