Strands Agents
AWS-backed open-source SDK for production AI agents with MCP, multi-agent patterns, and OpenTelemetry.
About
AWS released Strands Agents in 2025 as the open-source SDK its own teams, including Amazon Q Developer, use to ship production agents. The design is model-driven: rather than hand-coding an orchestration graph, you supply a model, a system prompt, and tools, and the agent loop handles planning, tool execution, context management, and streaming. First-class model providers include Amazon Bedrock, Anthropic, OpenAI, Gemini, and Ollama alongside custom providers, with Model Context Protocol servers for tool integration, agent-to-agent (A2A) communication, structured output, guardrail hooks, and multi-agent patterns. Observability is built on OpenTelemetry tracing with interception hooks, which matters for teams running agents behind real service-level commitments. The monorepo carries the Python SDK (pip install strands-agents, Python 3.10 or newer), a TypeScript SDK for Node 20 and up, the docs site, and CLI tooling, all Apache-2.0 licensed with about 6,700 GitHub stars. Quickstarts, API references, and deployment guides live at strandsagents.com.
Should you use Strands Agents?
Pick it when
Choose Strands when you deploy on AWS, use Bedrock models, and prefer a model-driven loop where you supply a prompt and tools instead of hand-coding an orchestration graph, with OpenTelemetry tracing for production.
Look elsewhere when
Skip it if you want orchestration defined as an explicit graph with checkpoints as the core design, where langgraph or google-adk fit, or if your organization standardizes on Azure, where Microsoft Agent Framework has the smoother path.
Alternatives to Strands Agents
- OpenAI Agents SDK
Similar lightweight primitives with handoffs and sessions, centered on OpenAI APIs rather than Bedrock, with a larger community by stars.
- Google Agent Development Kit
Adds graph workflows, evaluation tooling, and A2A, with native Gemini and Google Cloud deployment; more structure than a model-driven loop.
- LangGraph
Explicit graphs with cycles and persistence; more code to write, but predictable control where a model-driven loop may wander.
- Microsoft Agent Framework
The equivalent vendor stack for .NET and Python teams on Azure AI Foundry, with graph-based orchestration patterns.
