Haystack
Haystack is an open-source AI orchestration roof to develop production-ready LLM applications with Python. It makes it possible to design modular pipelines and agent workflows that provide open control over fetching, routing, memory, and production. Scalable RAG systems offer a transparent architecture for multimodal applications, semantic search, question-answer, and autonomous agents.
