Decision brief
LightRAG is a framework designed for efficient retrieval-augmented generation methods, focusing on enhancing the performance of large language models with additional knowledge.
Good fit when
- - When you need quick integration of external data sources to enrich your model outputs.
- ,- If your project values simplicity and speed in its implementation of retrieval-augmented generation techniques.
Avoid when
- - If you require a more complex framework offering advanced customization options, LightRAG’s core focus on simplicity might not meet your needs.
- - When the nature of your application demands real-time responses without room for the additional latency that might come with retrieval processes, despite being advertised as quick.
- Pricing:
- freemium - LightRAG is available under the MIT license and is free to use. Potential paid services or premium features may exist outside of this repository.
- Requirements:
- Min 4 GB RAM; Requires Python environment compatible with the version supported by LightRAG.; External datasets and relevant APIs may be required for full functionality.

Installation
💡 Using uv for Package Management: This project uses uv for fast and reliable Python package management. Install uv first: curl -LsSf https://astral.sh/uv/install.sh | sh (Unix/macOS) or powershell -c "irm https://astral.sh/uv/install.ps1 | iex" (Windows)
Note: You can also use pip if you prefer, but uv is recommended for better performance and more reliable dependency management.
📦 Offline Deployment: For offline or air-gapped environments, see the Offline Deployment Guide for instructions on pre-installing all dependencies and cache files.
Install LightRAG Server
- Install from PyPI
---
### Install LightRAG Server as tool using uv (recommended)
uv tool install "lightrag-hku[api]"
---
# Debian / Ubuntu (the official Docker image already includes this)
sudo apt-get install -y libcairo2
---
# Windows: install the GTK3 runtime, which bundles libcairo-2.dll
Deployments that never process markdown/textpack documents with embedded SVGs can ignore the startup warning.
Install LightRAG SDK
- Install from source code
cd LightRAG
---
# 或: pip install -e .
- Install from PyPI
uv pip install lightrag-hku
