Hands-On Comparison of Top Gen AI Frameworks for Go in 2026: Genkit, Eino, ADK Go and More
rseroter · x · 2026-09-30
Xavier Portilla Edo published an in-depth hands-on comparison of five Gen AI frameworks for Go: Genkit Go, Eino, Google ADK Go, tRPC-Agent-Go, and LangChainGo, each with real code and real output.
Framework positioning
- Genkit Go: typed Flows for observable pipelines, Dev UI on par with the TypeScript version, broad provider support
- Eino: flexible chains/graphs/callbacks, Eino ADK for agents and workflows, solid tooling
- Google ADK Go: enterprise-grade, agent-only focus with multi-agent orchestration, ADK Web embedded in your binary, Vertex AI gravity
- tRPC-Agent-Go: its GraphAgent is essentially LangGraph in Go
- LangChainGo: positioned as legacy, maintenance slowing
The article compares developer experience, abstraction levels, observability, provider support, and maintenance status, with guidance on which to choose. The author argues Go has quietly become the language of AI infrastructure — MCP servers, agent runtimes, model gateways — and by 2026 the framework-layer gap is closed, shifting the question from "Go or Python?" to "which Go framework?".
