## What it is
The source code for jsPerf.com, a web application for creating, sharing, and running JavaScript performance benchmarks in the browser. It is a Node.js application backed by MySQL and Redis that powers the public benchmarking site.

## Use cases
- run javascript performance benchmarks in the browser
- compare speed of different js code snippets
- self-host a jsperf instance
- share benchmark test cases with others
- contribute to the jsperf.com website

## When to choose
- you want to benchmark JavaScript code across browsers and share results publicly
- you want to run or contribute to the jsperf.com site itself

## When to avoid
- you need a general-purpose benchmarking library for Node.js code (use benchmark.js or vitest bench instead)
- you need offline or CI-based micro-benchmarking without a web app

## Facets
- artifact type: application
- maturity: maintenance
- function: benchmarking, web-framework, http-server
- domain: developer-tools, performance, web-development
- platform: self-hosted
- tags: jsperf, javascript-benchmarks, performance-testing, mysql, web-application, nodejs, web-server
