eino is a Go framework from CloudWeGo for building LLM and AI applications, positioned as a LangChain-style toolkit for the Go ecosystem. It is categorised as an agent framework, so it provides the structural pieces (agents, orchestration, application framework) needed to assemble LLM-powered applications in Go.

You want a Go-native, Apache-2.0 framework for LLM and agent application development rather than porting Python LangChain patterns by hand.

Use it to

  • Build LLM applications in Go
  • Develop agents within the CloudWeGo ecosystem
  • Adopt LangChain-style patterns in Go projects
  • Serve as a framework layer for AI tooling
