About
What is Haystack?
Haystack is an open-source AI orchestration framework designed for building context-engineered, production-ready LLM applications in Python. It enables developers to design modular pipelines and agent workflows with explicit control over retrieval, routing, memory, and generation. The framework is built for scalable agents, RAG systems, multimodal applications, semantic search, question answering, and conversational systems, all within a transparent architecture. Haystack is model- and vendor-agnostic, integrating with various LLM providers like OpenAI, Mistral, Anthropic, and local models. Its modular and customizable nature allows users to leverage built-in components or create their own, adding loops, branches, and conditional logic for precise control over context flow.
Best used for
Ideal for developers and data scientists who need to build production-ready LLM applications, design modular AI pipelines, and implement scalable RAG systems. Especially valuable for those requiring explicit control over retrieval, routing, memory, and generation in their AI workflows.
