Code Effects is a high-performance decision automation platform and business rules engine for .NET applications. It enables organizations to externalize complex business logic from application code, manage it centrally, and evaluate or execute decisions dynamically at runtime — without redeploying software. Designed for enterprise and regulated environments, Code Effects combines a web-based Rule Editor with a powerful Rule Engine. Rules are authored through an intuitive, natural language–like visual interface that allows business analysts, subject-matter experts, and developers to define, review, and maintain decision logic without writing code. At runtime, those rules execute as fully structured, strongly typed logic inside .NET applications, preserving accuracy, performance, and auditability. A unique capability of Code Effects is rule-to-query conversion. The same business rule used for single-object evaluation can also be applied as a dynamic LINQ filter against in-memory collections or database queries, enabling consistent decision logic across validation, search, analytics, and data filtering scenarios. Code Effects supports advanced decision modeling, including rule evaluation, rule execution, rule grouping, versioning, and reusable rule libraries. Its flexible data model allows rules to reference any .NET object, database schema, or external data source through extensible data providers. The platform scales efficiently for high-volume, low-latency workloads and supports multi-tenant and distributed architectures. Typical use cases include pricing and eligibility rules, underwriting and compliance validation, workflow routing, dynamic configuration, data filtering, and decision services for APIs and microservices. Code Effects is used by software vendors, financial institutions, insurers, government agencies, and enterprise IT teams that require predictable performance, governance, and long-term maintainability of decision logic in mission-critical systems. The platform is available in multiple licensing tiers, including a free engine edition for evaluation and internal use, as well as enterprise and source-code options for commercial distribution and regulated environments.
