haystack vs sparql-llm
haystack: Haystack is deepset's open-source Python framework for building LLM applications from modular pipelines and agents with explicit control over retrieval, routing, memory and generation. It is model- and vendor-agnostic and is widely used for RAG, semantic search, question answering and production agents.; sparql-llm: SPARQL-LLM provides tools to empower Large Language Models (LLMs) to generate accurate SPARQL queries for specific endpoints. It integrates Retrieval-Augmented Generation (RAG) and SPARQL query validation against endpoint schemas to ensure relevant and precise query generation on large-scale knowledge graphs.
TL;DR
- You need explicit, reproducible, and production-grade RAG pipelines in Python with granular control over document retrieval, reranking, and routing.
- You want vendor-agnostic LLM integration that can serve pipelines as REST APIs or MCP servers via Hayhooks under Apache-2.0.
- You want a visual no-code or low-code UI for business workflows without writing Python code; RAGFlow or MaxKB are much faster to deploy.
- You only need an end-to-end autonomous research agent that gathers sources and writes markdown reports; GPT Researcher is built for that out of the box.
