via “flow-based orchestration for multi-step ai workflows”
Open-source framework for building AI-powered apps in JavaScript, Go, and Python, built and used in production by Google
Unique: Combines flow definition with automatic OpenTelemetry instrumentation at the framework level, eliminating the need for manual span creation. Flows are first-class Registry objects that can be deployed as HTTP endpoints, CLI commands, or invoked from other flows without boilerplate. Uses language-native async patterns (async/await, goroutines, asyncio) rather than a custom DSL.
vs others: Provides deeper observability than LangChain's chains (automatic tracing vs manual instrumentation) and simpler deployment than Temporal/Airflow (no separate orchestration service needed for basic workflows).
