## What it is
Justice is an embeddable JavaScript script that renders an on-page toolbar showing web page timing metrics (page load, DOM interactive/complete, request count) with configurable performance budgets, plus a streaming FPS meter. It color-codes metrics against budgets to help teams spot performance issues during normal browsing.

## Use cases
- display page load performance metrics on my website
- monitor fps in the browser while browsing
- set performance budgets for dom complete and page load times
- track number of async requests a page makes over time
- let authenticated users see performance issues on our site
- embed a performance toolbar in a web app

## When to choose
- you want a lightweight, embeddable client-side performance indicator for developers or support staff
- you need simple budget-based color coding of timing metrics without a full RUM backend
- you want a quick FPS meter during front-end development

## When to avoid
- you need deep performance profiling or waterfall analysis (use browser dev tools)
- you need production RUM with data collection and dashboards
- you need a maintained tool - the project has not been updated since 2020 and the API may change

## Facets
- artifact type: library
- maturity: maintenance
- function: monitoring, analytics, developer-tools
- domain: web-development, frontend, performance, developer-tools
