Browser and CDN Caching Headers for Visitors
Sends Cache-Control headers on public pages for logged-out visitors, so a CDN or proxy can cache them for a few minutes.
Snippet Library
Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Browser and CDN Caching for Feeds and Sitemaps
Sends cache headers on RSS feeds and XML sitemaps so feed readers, crawlers and CDNs can reuse them for an hour instead of making WordPress rebuild them on every request.
Cache Public REST API Responses for Visitors
Stores the responses of public GET requests to the REST API (such as post lists used by headless front ends and block widgets) for a few minutes for logged-out visitors, and clears the cache when content changes.
Cache Site-Wide Comment Counts
Stores the comment totals that WordPress shows in the admin menu, toolbar and dashboard for 10 minutes, avoiding a slow counting query on every admin page view on sites with many comments.
Cache Slow Shortcodes With a Wrapper Shortcode
Adds a [cached] shortcode you wrap around any slow shortcode or content, such as [cached ttl="3600"][some_feed][/cached]; its output is stored for the time you choose and served from cache after that.
Cache User Counts on Large Sites
Caches the per-role user counts shown on the Users screen and dashboard for 12 hours, avoiding a heavy query on sites with many users.
Cache oEmbed Results Longer
Keeps embedded content like videos and social posts cached for 30 days instead of re-fetching it from the provider every day.
Cache-Busting Versions Based on File Changes
Replaces the version number on your theme's and plugins' CSS and JavaScript URLs with the file's last-modified time, so browsers and CDNs cache files for a long time but always fetch a fresh copy right after you change one.
Clear the Embed (oEmbed) Cache
Run on demand to delete every cached embed (videos, tweets and other oEmbed results) from the database, so they are fetched fresh and stale or broken embeds disappear.
Disable WooCommerce Cart Fragments Outside the Shop
Stops the cart fragments script, which fires an extra uncached AJAX request on every page, everywhere except the shop, product, cart and checkout pages.
Keep Speculative Loading Away From Cart, Checkout and Account Pages
Tells WordPress's built-in speculative loading (prefetching pages on hover) to skip cart, checkout and account pages, which are personal, never cached and expensive to build, so hovering over their links no longer costs server time.
Site Health Check for Compression and Browser Caching
Adds a Site Health test that requests your homepage and one of your theme's stylesheets and reports whether text files are compressed (gzip or Brotli) and whether static files get long browser cache lifetimes.
