Blaze and JRules are the longstanding leaders in the space, boasting the richest sets of features and the most enterprise customers. Corticon is a strong challenger with a different approach, and a very nice spreadsheet GUI for both developers and business users. Jess is the grandaddy of open source BRMS, while JBoss Rules is a newcomer with big momentum. The bottom line on the space in James Owen’s own words: I like Jess. I like JBoss Rules. But I like ILOG’s JRules better and I like Fair Isaac’s Blaze Advisor better. I might even like some of the others, like Haley who has the greatest interface in the world today, if they would let me test them out here in my lab and not just take their word for things. If I could pick and choose, it would be Haley’s interface, JRules for multiple options, Blaze Advisor / OPSJ for pure speed and natural language, JBoss Rules for pricing (and Mark Proctor) and their emphasis on all things technical via Wiki, and Jess because of Dr. Ernest Friedman-Hill and his worldwide support group. For all of the rule systems he’s able to get his hands on, James keeps a running set of benchmark results. You can follow the race right here. Technology Industry
