RagBuilder is a Python toolkit that automatically builds an optimal, production-ready Retrieval-Augmented Generation (RAG) pipeline for your data. It uses Bayesian hyperparameter tuning over chunking strategies, embedding models, and retriever types, evaluated against test datasets, and offers pre-defined state-of-the-art RAG templates.

Use cases

• automatically tune rag pipeline parameters for my documents
• find the best chunking strategy and chunk size for rag
• compare embedding models and retrievers for my dataset
• generate a synthetic evaluation dataset for rag testing
• deploy an optimized rag pipeline as an api
• build a production-ready rag setup from a pdf or url
• benchmark different rag configurations with bayesian optimization

When to choose

• you want to automatically find the best RAG configuration for your data instead of hand-tuning
• you need production-grade RAG pipelines with pre-built templates like graph retriever or contextual chunker
• you want to evaluate RAG setups against a test dataset with minimal code
• you want to deploy the resulting pipeline as an API service

When to avoid

• you need a fully managed hosted RAG service rather than a self-run Python toolkit
• your use case is simple retrieval without LLM generation
• you require a language other than Python or a framework outside the LangChain ecosystem
• you need fine-grained manual control over every pipeline component rather than automated optimization
