What others say about us

Everyday more people join the ultimate experience.

  • During my tenure as a Software Architect at the New York City government (on a project of issuing street permits for various work natures) which involves large number of business rules, one of my prime responsibility was to evaluate and suggest .NET based business rule engine at an enterprise level. I have evaluated many including Flex Rule and liked the same for its powerful forward chaining Inference Engine (RETE based) & its XML based features.. I was looking at a tool, which not only has a less learning curve but also easy to deploy and maintain for future operations, where in, the Flex Rule won may votes. The rule tester is a neat feature , any non-developer community can test and verify the rules. The POC using Flex Rule won lot of appreciation in our business groups. Our project is modeled using .NET MVC3 , and we marked Flex Rule as a good choice to blend with the overall architectural aspects. The cost effectiveness of Flex Rule for at the level of enterprise Business Rule Engine is very impressive, the API is very easy to learn by mid – senior developers. Flex Rule, indeed a very good choice for those who is looking at the enterprise level business rule engines in .NET world

  • TATI required a fast and flexible BRE for integration into our Regulatory Information Management System product. Our existing rules engine was difficult to manage and extend to meet our growing customer requirements. We looked at several BRE products in the .Net space; none matched FlexRule’s capabilities or value. The BRE is lightweight and simple to deploy, and the designer enables non-developers to easily create and modify rules with minimal training. This is hands-down the best BRMS to-date and Pliant’s product support has been outstanding.

  • At TriPartum, we needed a rules engine that would be flexible, easy to learn and not impair the performance of our document processing service. We evaluated all the .NET based products on the market but nothing came close to the flexibility and cost-effectiveness that FlexRule was able to provide. Additionally, Pliant Framework really helped us out during our evaluation period.

  • Pliant has developed a flexible workflow product that we are using to implement work flow in our product. As one of their first customers we have had a number of issues that the develop team has resolved promptly. They are great folks to work with and we see ourselves as having a true partner in Pliant. We see no need to look for other vendors in the area of work flow and business rules functionality.
