WebCacheWarmer
Web Cache & Performance Tool
Only for Mac
$3.99
Mac
Warm your website's cache, measure cold vs. cached response times, detect your CMS, discover sitemaps, and export detailed performance reports.
WebCacheWarmer is a native macOS developer tool that crawls your website to warm its page cache, then verifies cache effectiveness by measuring response times before and after caching.
HOW IT WORKS
WebCacheWarmer performs a two-pass crawl. The first pass ("warming") visits every page to trigger cache generation and measures cold response times.
The second pass ("verifying") re-visits the same pages to measure cached response times. You get a clear before-and-after comparison showing exactly how much your caching layer improves performance.
