Pricing	freemium	free
Strengths	+ Explicit, debuggable graph model for complex flows + Mature Python ecosystem + Tight LangSmith integration	+ Unified, provider-agnostic API across many model vendors + First-class streaming and UI integration for web frameworks + Strong TypeScript ergonomics and type safety + Free and open source with a large, active community
Tradeoffs	− Steeper learning curve than linear agent SDKs − LangChain abstractions are opinionated	− TypeScript/JavaScript only, with no Python support − Lighter-weight than full agent-orchestration frameworks for complex flows
