Strands Agents

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.
