Basic Information

RAGLight is a lightweight, modular Python library designed to implement Retrieval-Augmented Generation (RAG) workflows and related pipelines. It is intended for developers who want to build context-aware AI applications by combining document retrieval and language generation. The repository provides ready-made pipelines (RAG, Agentic RAG, RAT), a CLI wizard to index documents and chat with a knowledge base, a Builder for custom pipelines, and examples for ingesting data from local folders and GitHub repositories. It supports multiple LLM providers and embedding backends and includes configuration classes to control indexing, model selection, vector store settings, and ignore-folder rules. Docker examples and environment variable options are provided to configure connections to local or remote LLM services. The project targets teams and engineers integrating retrieval, reasoning, and optional external tool access into conversational or generative systems.

App Details

Features
The README documents several key features: Embeddings model integration with examples such as HuggingFace all-MiniLM-L6-v2. LLM-agnostic design supporting providers like Ollama, LMStudio, vLLM, OpenAI, Mistral and Google Gemini. A RAG pipeline that unifies retrieval and generation, an RAT pipeline that adds a separate reasoning LLM and reflection steps, and an Agentic RAG pipeline that adds an agent able to query the vector store. MCP integration enables external tool access via MCP servers. Flexible document ingestion supports PDFs, text, DOCX and code files. Vector store support includes Chroma with persistence and collection management. Usability features include a CLI wizard, ignore_folders configuration, a Builder for custom pipelines, code ingestion that extracts signatures, and example Dockerfiles.
Use Cases
RAGLight helps developers prototype and deploy retrieval-augmented and agentic generation systems quickly by providing modular components and example workflows. The library automates document ingestion and indexing, offers configurable ignore-folder lists to avoid irrelevant files, and exposes similarity search and class-aware searches for code bases. Users can swap embeddings, vector stores, and LLM backends to match local or cloud infrastructures and can run an interactive CLI to build a knowledge base and start a chat without writing code. Agentic RAG and RAT pipelines provide options for iterative reasoning and reflection, while MCP integration allows the agent to call external tools for code execution or database access. Docker examples and environment variable configuration facilitate reproducible deployments and integration with local LLM services.
