Why Strands?

• Simple — A minimal agent loop that just works. No boilerplate, no complex abstractions.
• Model agnostic — Amazon Bedrock, Anthropic, OpenAI, Gemini, Ollama, LiteLLM, llama.cpp, and more. Swap providers in one line.
• Multi-agent built in — Coordinate agents with Graph, Swarm, and Workflow patterns — plus A2A protocol for cross-framework interop.
• Native MCP — First-class Model Context Protocol support gives your agents access to thousands of tools.
• Production ready — Deploy to AWS Lambda, Fargate, EKS, Bedrock AgentCore, Docker, Kubernetes, or Terraform with built-in OpenTelemetry observability.
• Conversational & beyond — Streaming, non-streaming, autonomous agents, structured output, and real-time bidirectional audio conversations.
