gorango/flowcraft

Supports declarative, serializable workflow blueprints with nodes and edges that scale from in-memory execution to distributed systems via pluggable adapters (BullMQ, AWS SQS, Kafka, RabbitMQ, etc.). Built-in resilience patterns include retries, fallbacks, timeouts, and human-in-the-loop constructs, while static analysis tools validate blueprints and generate Mermaid diagrams. Zero dependencies, fully TypeScript-typed, with extensible loggers, serializers, evaluators, and middleware for custom integrations.
