AWS open-sources Strands Harness, claims 77% lower cost than Claude Code
dl_weekly · x · 2026-09-30
AWS launched Strands Harness, an open-source AI agent aimed at the "works locally, breaks in the cloud" problem: developers prototype agents with tools like Claude Code and Codex, then hit walls scaling to cloud environments.
- A complete, ready-to-use agent that runs locally or in any cloud—Google Cloud, Azure, Modal, Cloudflare, and beyond AWS
- Built on AWS's open-source Strands SDK for multi-agent patterns; supports frontier models from Anthropic, OpenAI, Amazon Bedrock, and Google, or a local Ollama model
- Ships with read/write/edit, shell, and web search tools, relying on tools the underlying model already knows instead of bespoke per-task tooling
- AWS claims 26% better efficiency and 77% lower cost than Claude Code on identical tasks (vendor claims, not independently verified)
