Flowcraft is a workflow orchestration framework for building, executing, and monitoring durable workflows. It provides a type-safe, composable API for defining workflows as directed graphs of nodes and edges, supporting both programmatic (fluent) and declarative (JSON) definitions. The framework enables progressive scaling from in-memory execution to distributed systems via adapters for message queues and cloud services, with built-in support for patterns like retries, timeouts, human-in-the-loop, batch processing, and subflows. Key architectural pieces include a dependency-free core runtime, a sophisticated context tracking system for efficient state persistence, a plugin-based adapter architecture for distributed execution, and LLM tooling for workflow introspection and control via natural language.
