Strand Agents Strand Agents
Strands Agents is an open-source, model-driven SDK for building and running production AI agents in Python and TypeScript with just a few lines of code. It pairs any model with tools via an agent loop, and the newer Strands harness offers a fully assembled, deployable general-purpose agent.
Strands harness launched September 21, 2026, claiming 28% lower token cost across six benchmarks and 77% lower cost than Claude Code on Terminal-Bench 2.1 with Fable 5; Strands Agents SDK originally introduced May 16, 2025, with 6,700+ GitHub stars.
As of
- Model-agnostic support for Amazon Bedrock, Anthropic, OpenAI, Gemini, Ollama, and LiteLLM
- Agent loop with invocation limits, cancellation, stop reasons, and concurrent invocations
- Hooks to intercept, log, validate, or redirect any step in the loop
- Built-in MCP, streaming, multi-agent patterns, and structured output
- Sandbox support (e.g., DockerSandbox) for safe shell/code/file execution
- Strands harness with prompt caching and context management defaults (truncation, compaction, recovery)
- Python 3.10+ and Node.js 20+ SDKs with tools, memory, and observability
Developers and teams building production-grade, model-agnostic AI agents who want end-to-end control over context, tools, and deployment across local and cloud environments.
Users seeking a no-code or fully managed agent platform, or those unwilling to handle model API costs, credentials, and tool security auditing themselves.
Strands Agents is a free, open-source SDK released under the Apache 2.0 license, with no paid tiers or credit models; users only pay for the underlying model API usage (e.g., Bedrock, Anthropic, OpenAI, Google, Ollama).
Strands Agents offers a powerful, Apache 2.0-licensed, model-agnostic foundation with strong production controls and a cost-efficient harness, though it requires developer expertise and self-managed model costs and tool security.
