manzanas vs harness-sdk

Q: Which is better, manzanas or harness-sdk?

By GitHub stars, harness-sdk has more community adoption, but the best choice depends on your specific use case.

manzanas: Manzanas is a macOS daemon that orchestrates fleets of iOS simulators, enabling multi-agent and human users to share and interact with them efficiently. It offers features like simulator leasing, action execution, live streaming, and a detailed run journal for deterministic testing and evidence collection.; harness-sdk: This monorepo holds the Strands Agents SDKs for Python and TypeScript plus Strands harness, a fully assembled agent created with one create_harness() call. It runs in your own process and covers the agent loop, tools, MCP, multi-agent patterns, memory, sessions, guardrails, tracing and evals across Bedrock, Anthropic, OpenAI, Gemini and other providers.
