Haystack is an AI orchestration framework for building production-ready applications with large language models.
It lets developers design modular pipelines and agent workflows for retrieval-augmented generation, semantic search, question answering, conversational systems, multimodal applications, and other context-driven AI use cases. The framework is written for Python projects and focuses on explicit control over retrieval, routing, memory, tool use, and generation.
This is free and open source software.
Key Features
- Build modular pipelines for retrieval, ranking, filtering, routing, and generation.
- Create agent workflows with transparent control over memory, tools, and model interactions.
- Use Haystack for RAG systems, semantic search, question answering, and conversational applications.
- Integrate with a wide range of model providers, including OpenAI, Anthropic, Cohere, Hugging Face, Azure OpenAI, AWS Bedrock, and local models.
- Extend applications with custom components and community integrations.
- Install with pip or use supported deployment methods such as Docker images.
