# LightRAG vs sglang

LightRAG and sglang share 4 technologies: FastAPI, Redis, OpenAI, and Anthropic. Both are written in Python.

- [HKUDS/LightRAG](https://seerepo.com/r/HKUDS/LightRAG): [EMNLP2025] LightRAG: Simple and Fast Retrieval-Augmented Generation
- [sgl-project/sglang](https://seerepo.com/r/sgl-project/sglang): SGLang is a high-performance serving framework for large language models and multimodal models.

## What they share and what sets them apart

- In common: FastAPI, Redis, OpenAI, Anthropic
- Only in LightRAG: React, Vite, Postgres, MongoDB
- Only in sglang: axum

## Side by side

| | LightRAG | sglang |
|---|---|---|
| Size | 442,998 lines written, 338 code files | 3,187,732 lines written, 4,539 code files |
| Who writes it | 19.8% of its commits signed by AI. With Claude Code, Codex, GitHub Copilot, Cursor, and Jules | 8.3% of its commits signed by AI. With Claude Code, Gemini CLI, Cursor, GitHub Copilot, Codex, Devin, CodeRabbit, and OpenHands |
| Activity | Last push October 29, 2026, 8,260 commits, 40,452 stars | Last push November 1, 2026, 21,411 commits, 38,327 stars |
| Tests | 676 test files. 66% of its code files have a test that imports them | 4,053 test files. 57.8% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
