# sglang vs x-algorithm

sglang and x-algorithm share 10 technologies: axum, FastAPI, tower, Redis, Tokio, tracing, psutil, prometheus-client, tracing-subscriber, and OpenTelemetry. sglang is written in Python and x-algorithm in Rust.

- [sgl-project/sglang](https://seerepo.com/r/sgl-project/sglang): SGLang is a high-performance serving framework for large language models and multimodal models.
- [xai-org/x-algorithm](https://seerepo.com/r/xai-org/x-algorithm): Algorithm powering the For You feed on X

## What they share and what sets them apart

- In common: axum, FastAPI, tower, Redis, Tokio, tracing, psutil, prometheus-client, tracing-subscriber, OpenTelemetry

| Tests | 4,212 test files. 59.6% of its code files have a test that imports them | 19 test files. 1.1% 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.
