deepset-ai/haystack
Open-source AI orchestration framework for building context-engineered, production-ready LLM applications. Design modular pipelines and agent workflows with explicit control over retrieval, routing, memory, and generation. Built for scalable agents, RAG, multimodal applications, semantic search, and conversational systems.
This framework helps AI developers build custom applications that leverage large language models (LLMs). It allows you to design specific workflows that process information, retrieve relevant data, and generate responses. Developers use it to create intelligent systems like advanced search, question-answering, and conversational AI.
24,487 stars. Used by 11 other packages. Actively maintained with 155 commits in the last 30 days. Available on PyPI.
Use this if you are an AI developer looking to build, customize, and deploy robust LLM-powered applications in a production environment.
Not ideal if you are looking for a ready-to-use application and do not have programming experience to integrate and develop with a framework.
