## What it is
A Node.js library that uses PhantomJS to render webpages, capture screenshots, and diff DOM changes (added/removed elements, text, and style changes) over time. It stores capture history and can show diffs between any two snapshots.

## Use cases
- monitor a webpage for DOM changes over time
- capture webpage screenshots and diff them
- detect when page content or styles change
- track element additions and removals on a site
- build a UI showing history of page changes

## When to choose
- you need headless webpage capture with DOM diffing on an older Node.js stack
- you want screenshot-based visual change detection with a companion UI (pmui)

## When to avoid
- you need a maintained tool - it depends on the deprecated PhantomJS and hasn't been updated since 2020
- you need modern browser automation - use Puppeteer or Playwright instead
- you're on Windows and rely on npm-installed PhantomJS, which can't be spawned
