Haystack
Haystack is an open-source AI framework for building production-ready agents, RAG, and context engineering applications.
Description
Haystack is an open-source AI orchestration framework designed for building production-ready applications powered by large language models (LLMs). It provides a modular and composable architecture for constructing complex AI workflows such as retrieval-augmented generation (RAG), AI agents, conversational AI, multimodal AI, and content generation. The framework offers full visibility into every decision made by the AI, allowing developers to inspect, debug, and optimize each step. Haystack integrates seamlessly with a wide range of external services including OpenAI, Anthropic, Mistral, Hugging Face, Weaviate, Pinecone, Elasticsearch, and more, without vendor lock-in. It supports rapid prototyping and deployment with unified tooling, and scales to enterprise-grade reliability with serializable, cloud-agnostic, Kubernetes-ready pipelines equipped with logging and monitoring. The ecosystem includes community support, enterprise support with private engineering and best-practice templates, and an AI orchestration platform with visual pipeline design, data management, and secure access controls.
Features
Modular and composable architecture for building transparent, context-engineered AI systems. Full visibility to inspect, debug, and optimize every decision the AI makes. Integrates with a wide range of AI stacks including OpenAI, Anthropic, Mistral, Hugging Face, Weaviate, Pinecone, Elasticsearch, and more, with no vendor lock-in. Supports rapid development from prototype to production using the same building blocks. Pipelines are serializable, cloud-agnostic, and Kubernetes-ready, with built-in logging, monitoring, and deployment guides. Supports advanced RAG, AI agents, multimodal AI, conversational AI, and content generation use cases. Standardized tool calling and scalable context engineering for production-ready AI agents. Flexible pricing and enterprise support options available.
