Choose Go Micro if you're a Go developer building a complete agent system with durable workflows and cross-framework interop; it's free and open-source, but Go-only. Choose Spider Cloud if you need a fast, reliable web data extraction layer for any AI agent or RAG pipeline, regardless of language; its freemium model and Rust engine make it cost-effective and easy to integrate. They can even complement each other: use Spider Cloud to feed web data into a Go Micro agent.
