About Strands Agents SDK
Strands Agents SDK is an open-source toolkit for building and controlling production AI agents in Python and TypeScript. It operates in the user's local process with no hosted control plane, and includes built-in functionality for agent lifecycle management, tool integration, structured output, and observability. The SDK is model-agnostic, compatible with any AI model and cloud provider, and offers prebuilt harnesses for Python and TypeScript that provide optimized default configurations for models, tools, memory, and context management. Lower-level SDK packages are also available for users who want to customize the agent loop directly.
