Haystack AI

Open-source AI orchestration framework for Python developers: build, customize, and deploy production-grade LLM applications (RAG, agents).

Haystack is the open-source AI orchestration framework from deepset, designed for Python developers building production-ready LLM applications. Its modular architecture uses components (retrievers, generators, agents) to create flexible pipelines for advanced use cases: Retrieval-Augmented Generation (RAG) and autonomous agents. The framework integrates smoothly with major providers (OpenAI, Anthropic) and vector databases (Pinecone, Weaviate), providing the control and tooling necessary to move projects from prototype to enterprise-scale deployment.
