OpenRules Reviews, Pricing, Features & Alternatives in 2026
OpenRules is a business rules management system that allows you to create, test, and deploy complex decision models using familiar tools like Microsoft Excel, Google Sheets, or simple tables.
OpenRules provides a practical way for you to manage complex business logic without needing deep programming knowledge. You can define your business rules and decision tables directly in Excel or Google Sheets, making it easy for subject matter experts and developers to collaborate on the same logic. This approach reduces the risk of miscommunication and speeds up the transition from business requirements to a working production system.
The platform excels in high-performance environments where you need to execute millions of transactions with minimal latency. You can deploy your decision models as RESTful web services on-premise or in the cloud using AWS Lambda, Azure Functions, or Google Cloud Functions. It is particularly effective for organizations in finance, insurance, and healthcare that handle intricate, high-volume decision-making processes daily.
