Haystack
Open-source framework for building production-ready RAG and LLM applications with modular pipelines
About
Haystack is an open-source AI orchestration framework by deepset designed for building production-ready LLM applications. It offers modular, composable pipelines for RAG (Retrieval-Augmented Generation), semantic search, conversational AI, and agentic workflows with explicit control over retrieval and generation steps. Built for developers who need flexibility and transparency, it integrates with major LLM providers, vector databases, and document processors while remaining framework-agnostic and self-hostable.
