LightRAG

LightRAG indexes documents into a knowledge graph plus vector store and queries both layers, as a lighter alternative to Microsoft GraphRAG. The server package ships a REST API, a web UI for inserting and visualizing the graph, and Ollama-compatible /api routes for chat frontends. Parsing runs via MinerU, Docling or a native engine; production storage goes to PostgreSQL, Neo4j, MongoDB, Milvus or OpenSearch.

Who it is for: developers wanting graph-based RAG with a ready server

Strengths

  • Dual-level graph and vector retrieval with fewer LLM calls than community-report GraphRAG
  • Incremental updates and document deletion with graph regeneration from the LLM cache
  • Three parsing engines and four chunking strategies, including paragraph-semantic
  • Separate LLM settings per role: extract, query, keywords and VLM

Weaknesses

  • Default KV, vector and graph stores are in-memory with file persistence, not for production
  • Server binds 0.0.0.0 with every endpoint public until auth is configured
  • Ollama-compatible /api routes stay open even with auth unless WHITELIST_PATHS is set
  • docx smart headings and SVG rendering need extra spaCy models and libcairo
  • no GPU
  • Docker + Compose
  • Needs PostgreSQL (recommended for production), Neo4j (optional), MongoDB (optional), Milvus (optional), OpenSearch (optional)
  • Models: LLM and embedding providers configured in .env, tested with open models such as Qwen3-30B-A3B

Open Notebook

Open Notebook collects PDFs, audio, video, web pages and Office files into notebooks and offers cited chat, full-text and vector search, notes and multi-speaker podcast generation. It runs as two containers (SurrealDB plus a FastAPI/Next.js app) and talks to OpenAI, Anthropic, Google, Mistral, Groq, Ollama, LM Studio or any OpenAI-compatible server. A REST API and MCP integration expose the same features.

Who it is for: individual researchers who want a private NotebookLM

Strengths

  • 20+ providers, including Ollama and LM Studio for fully local runs
  • Podcasts with 1 to 4 speakers and custom episode profiles
  • REST API on port 5055 and an MCP server for Claude Desktop or VS Code
  • Two-service Docker Compose; keys stored encrypted with OPEN_NOTEBOOK_ENCRYPTION_KEY

Weaknesses

  • Single-user; multi-user support is only a future direction in VISION.md
  • No password by default and ports 8502/5055 bind to all interfaces
  • Anthropic and Groq offer no embeddings, so a second provider is needed
  • UI in 14 languages but provider setup is manual per model type
  • no GPU
  • Docker + Compose
  • Needs SurrealDB
  • Models: OpenAI, Anthropic, Google, Mistral, Groq, DeepSeek, xAI, OpenRouter, Cohere, Ollama, LM Studio, oMLX and any OpenAI-compatible endpoint
  • port 8502
  • README: alternative to NotebookLM
