Updated
•1 min read
AWS open-sourced a model-driven AI agent SDK. Here's why it's different from LangChain, LlamaIndex, and CrewAI.
Summary
AWS Strands Agents is an open-source (Apache 2.0), model-driven SDK for building AI agents in Python and TypeScript. Instead of writing imperative orchestration logic, you declare the agent's intent, tools, and model — the LLM handles execution. This guide covers core philosophy, key features (20+ pre-built AWS tools, MCP support, multi-agent patterns), a comparison table vs LangChain/LlamaIndex/CrewAI, real-world use cases in DevOps and data pipelines, and a hands-on getting started tutorial.
