Prolog Services

We helped develop, maintain, integrate and/or migrate some of the largest Prolog applications in the world, over decades and until this day. We have ample field experience with SICStus, SWI, XSB, YAP and other Prologs, as well as in integrating with Java, Javascript, Python, SQL and more.

Logic Production Systems

We’ve been contributing to this open source project for a new language that attempts to unify imperative and logic programming.  Visit our reference demo web site to experience it:

Prolog Studio

Do you write XSB Prolog code? An open source IDE for XSB Prolog and derived higher level languages. XSB Prolog is a uniquely powerful logic engine, and now Studio is its most advanced developer tool.

It takes 5 minutes to ['watch the quick tour', download, install]. Go to the Prolog Studio page.

Java/Prolog SDK

An open source library to enable Java apps to use XSB Prolog engines, and vice-versa.
