harness-sdk vs trpc-agent-go

Q: Which is better, harness-sdk or trpc-agent-go?

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

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.; trpc-agent-go: tRPC-Agent-Go is a Go-native framework for production agent systems. It combines LLM agents, type-safe graph workflows (positioned as a LangGraph equivalent for Go), chain, parallel and cycle multi-agent patterns, function and MCP tools, session and memory state, knowledge retrieval, SKILL.md-based agent skills with self-evolution, evaluation sets, and OpenTelemetry/Langfuse observability, with A2A and AG-UI protocol integration.
