what does our expert say about Haystack?
Haystack stands out because it gives you real control over how your AI applications work. The modular design makes it easy to test, improve, and scale workflows without being locked into one provider. I found the integrations with different AI models and vector databases especially useful for building flexible RAG systems. The documentation is also well organized, which helps during development. The main drawback is that beginners may need some time to understand its components and pipelines. Once you get past that learning curve, Haystack becomes a powerful framework for creating reliable AI agents and production-ready applications.
