You can evaluate OpenRules Decision Manager for free by installing it from AWS Marketplace following these instructions. You only need to have a free AWS account and your first free 30,000 executions should be more than enough for the product evaluation. You may easily cancel your AWS subscription at anytime.
Upon request, we also may provide you with an evaluation version that doesn’t report your executions to the AWS metering service. It removes a related overhead allowing you to test the actual high performance of the OpenRules decision engine.
