## Health v2 (maintenance only)
Score: 86/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 91, release rhythm 71, longevity 100
- inputs: {"age_days": 2973, "days_push": 55, "days_rel": 112, "gap_med": 34.0, "n_releases_24m": 13}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A dataset and npm module that classifies third-party web entities (advertising, analytics, social, etc.) and quantifies their JavaScript execution cost on the web, derived from HTTP Archive crawls analyzed with Lighthouse and BigQuery. It also includes a web UI for exploring which third-party scripts have the greatest performance impact.

## Use cases
- identify which third-party scripts slow down my website
- look up which entity owns a third-party script URL
- find the most expensive third-party scripts on the web
- decide which analytics or ad scripts to include on a page
- analyze web performance impact of third parties from HTTP Archive data
- categorize third-party domains by provider

## When to choose
- you need categorized data on third-party script origins and their performance cost
- you want to audit a page's third-party scripts for performance impact
- you're doing research on the web's third-party ecosystem

## When to avoid
- you need real-time runtime monitoring of third-party scripts in production
- you want a tool that blocks or manages third-party scripts rather than classifying them
- you need first-party performance profiling

## Facets
- artifact type: dataset
- maturity: active
- function: analytics, developer-tools, data-science
- domain: web-development, analytics, performance, developer-tools
- platform: cli
- tags: third-party-javascript, http-archive, lighthouse, web-performance, npm-module, bigquery, nodejs, web-server
