Q: Which is better, open-multi-agent or harness-sdk?

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

open-multi-agent: OMA (Open Multi-Agent) is a self-hosted TypeScript runtime for single agents, task pipelines and goal-planned teams. Consequential actions pause for durable approvals bound to a hash of what the reviewer saw, and every run leaves a record that can be verified offline.; 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.
