Overview

Eino is a Go framework for LLM applications, modeled on LangChain and Google ADK but following Go conventions. It provides component interfaces (ChatModel, Tool, Retriever, Embedding), an Agent Development Kit with ReAct agents, a multi-agent DeepAgent and interrupt/resume, and a compose package for typed graphs and workflows. Component implementations live in the separate eino-ext repo.

Who it is for: Go developers building agents and LLM pipelines in code

Strengths

Typed graph and workflow composition, with graphs exposable as agent tools
Handles stream concatenation, merging and copying between nodes automatically
Interrupt/resume with checkpoints for human-in-the-loop agents
Official integrations for OpenAI, Claude, Gemini, Ark, Ollama and Elasticsearch

Weaknesses

Go only; no Python or TypeScript bindings
Component implementations are in a separate eino-ext repository
README documentation links point to the Chinese-language manual path
No built-in UI; visual debugging is a separate devops module

What it needs

no GPU
Needs Go 1.18+
Models: OpenAI, Claude, Gemini, Ark, Ollama

How to choose

Pick by language first (Python or TypeScript), then by how much the framework hides.
Check how it handles tool errors and retries; that is where agents break in production.
Look for tracing hooks so you can see each step later.
