RuleFlow

RuleFlow is a lightweight, developer-friendly rule engine for .NET.

It focuses on simplicity, performance, and explainability.

Quick example

var order = new Order { Amount = 1500 };

var rules = RuleSet.For<Order>("ApprovalRules")
    .Add(Rule.For<Order>("High amount")
        .When(o => o.Amount > 1000)
        .Then(o => o.RequiresApproval = true)
        .Because("Amount exceeds threshold"));

var engine = new RuleEngine();
var result = engine.Evaluate(order, rules);

// Async-first path for server workloads:
// var result = await engine.EvaluateAsync(order, rules);

Features

Fluent API
Conditional chains (ThenIf)
Explainability (execution records, tree and JSON formatters)
Observability — optional metrics and custom observer callbacks (zero overhead when disabled)
Async support (conditions and actions)
Rule groups
Dynamic conditions — structured, JSON-friendly ConditionNode trees (no expression parsing)

Dynamic conditions

RuleFlow supports user-defined rules via structured conditions (JSON, database, or UI): ConditionLeaf / ConditionGroup, pluggable operators, and dotted nested property paths (e.g. Customer.Name) resolved with cached reflection.

See the full documentation: Dynamic conditions.
