A production-minded framework for building composable RAG and LLM search pipelines.

Start LearningReviewed July 3, 2026

Overview

Haystack is an open-source framework aimed at production LLM applications, especially search and RAG. Its documentation teaches the pipeline/component model — how to wire retrievers, rankers, prompt builders, and generators into robust, branching pipelines — plus integrations with vector stores and models. It's a strong, well-engineered alternative to LangChain/LlamaIndex when you value explicit, composable pipelines.
