FreemiumOpen-source framework for building production AI agents and RAG
What is Haystack?
Haystack is an open-source Python framework from deepset for building agentic and retrieval-based AI applications. It offers modular components for pipelines, retrieval and agents, plus integrations with many model providers and vector stores, for developers shipping production systems.
Applications are assembled from building blocks that can be swapped and customized, which keeps them transparent and testable. The project offers tutorials, a cookbook, documentation and an ambassador program, and its site promotes a course on building AI agents.
deepset also sells Haystack Enterprise, with a platform, trial and paid support for teams that want help running Haystack in production. The framework itself is free to use.
