Haystack
Open-source framework for building production-ready search and RAG (retrieval-augmented generation) applications with LLMs.
Overview
Haystack provides composable building blocks - document retrieval, embedding, ranking, generation - for building LLM-powered search and question-answering pipelines, with connectors to many vector databases, document stores, and model providers. It's designed around explicit, inspectable pipelines rather than a single black-box abstraction.
Haystack is a fit for teams building retrieval-augmented generation or enterprise search applications specifically, a more focused alternative to LangChain's (also in this catalog) broader general-purpose LLM application framework.
