About this plugin
Coverage Assistant is a companion plugin for Static Cache Wrangler that helps you monitor which posts and pages have been cached as static HTML files.
Get instant visibility into your static cache coverage with a modern, card-based dashboard that shows:
- Coverage Percentage – See at a glance what % of your content is cached
- Uncached Content List – Identify exactly which pages need caching
- One-Click Copy Links – Copy uncached URLs to clipboard for manual caching
- GUI Crawler – Interactive browser-based crawler unlocks at 65% coverage
- Cache Statistics – View total files, cache size, and more
Perfect for site owners who want to ensure complete static site generation before deploying to CDN, Amazon S3®, or creating offline copies.
Key Features

- Coverage Cards – Color-coded indicators (green/yellow/red) for quick status checks

- One-Click Copy Links – Copy uncached URLs to clipboard for manual caching
- GUI Crawler – Interactive browser-based crawler with progress tracking (unlocks at 65% coverage)

- Recently Cached – See the last 10 pages that were successfully cached
- Auto-Cache Command – Use wp scw crawl-uncached to automatically cache all remaining pages
- WP-CLI Integration – Full command-line interface for coverage monitoring and automation
