The Production-Ready
Open Source AI Framework

Get Started

Highly
customizable

Don’t just use Haystack, build on top of it.

The flexible components and pipelines architecture allows you to build around your own specifications and use-cases. Whether you’re building a simple retrieval-augmented generation (RAG) app or a complex architecture with many moving parts.

Build with leading LLM providers and AI tools

Have the freedom of choice.

Thanks to our partnerships with many leading LLM providers, vector databases, and AI tools such as OpenAI, Mistral, Weaviate, Pinecone and so much more

Production is where it gets real

Get your application in front of the world.

Haystack 2.0 is built from the ground-up with production in mind. Our pipelines are fully serializable and perfect for K8s native workflows. Logging and monitoring integrations give you the transparency you need. Our deployment guides walk you through full-scale deployments on all clouds and on-prem.

Learn how to extend Haystack with deepset Cloud for faster building, easier iteration and instant deployment.

Haystack Use Cases

Advanced
RAG

Build highly performant RAG pipelines with a multitude of retrieval and generation strategies. From hybrid retrieval to self-correction loops, Haystack has got you covered.
Multimodal
AI

Architect a next generation AI app around all modalities, not just text. Haystack can do tasks like image generation, image captioning and audio transcription too.
Conversational
AI

All of our generators provide a standardized chat interface so that you can focus on building the perfect bot for your users.
Content
Generation

The flexibility and composability of Haystack’s prompt flow is unparalleled. Leverage our Jinja-2 templates and build a content generation engine that exactly matches your workflow.
Agentic
Pipelines

All our LLM generators come with a standard function-calling interface so that your LLM can leverage tools to achieve more. Our pipeline architecture provides branching and looping to support complex agent workflows.
