About Haystack
Haystack is designed for teams building production-oriented LLM applications such as RAG systems, question answering tools, semantic search, and conversational assistants. Its value comes from treating LLM applications as configurable pipelines made of retrievers, generators, converters, and supporting components. That makes it useful for organizations that want more explicit architecture and customization than a simple prompt wrapper provides. Haystack is often evaluated when a team needs to connect data sources, retrieval infrastructure, and models into a deployable application workflow.
