Decision Guide: When to Choose haystack vs Switch
+ When haystack is the Best Choice
- You need explicit, reproducible, and production-grade RAG pipelines in Python with granular control over document retrieval, reranking, and routing.
- You want vendor-agnostic LLM integration that can serve pipelines as REST APIs or MCP servers via Hayhooks under Apache-2.0.
! When to Look for Alternatives
- You want a visual no-code or low-code UI for business workflows without writing Python code; RAGFlow or MaxKB are much faster to deploy.
- You only need an end-to-end autonomous research agent that gathers sources and writes markdown reports; GPT Researcher is built for that out of the box.
