Haystack by deepset
Haystack is an open source AI framework developed by deepset that enables developers and teams to build production-ready AI agents, Retrieval-Augmented Generation (RAG) systems, and context-engineered applications. With over 25,000 GitHub stars, Haystack has established itself as a leading framework in the AI development ecosystem.
The framework provides a modular architecture that gives developers full visibility into every step of their AI workflows - from retrieval to reasoning to memory and tool use. This transparency allows teams to inspect, debug, and optimize every decision their AI systems make.
Haystack is trusted by major enterprises across industries including Accenture, NVIDIA, Airbus, AWS, Comcast, Lufthansa Industry Solutions, and many more, demonstrating its reliability for enterprise-grade AI applications.
The framework can be easily installed via pip (pip install haystack-ai) and offers comprehensive documentation, tutorials, cookbooks, and courses through partnerships with DataCamp and DeepLearning.AI.
