Why it matters

Framework choice shapes development. Understanding options prevents wrong-tool syndrome.

The architecture

LangChain: broad tool library, many integrations, complex abstractions.

LangGraph: state machine for agents, more controlled.

How it works end to end

Google ADK: Python + Java. Gemini-optimized. Session + memory abstractions.

CrewAI: multi-agent focused; role-based agent teams.

Home-grown: for simple cases, direct LLM API + custom loop can be cleaner.

DSPy: programming with LLMs; different paradigm.
