Clean Up the Page Head
Removes rarely used tags from the page head: RSD, Windows Live Writer manifest, shortlink, adjacent post links and the REST API discovery link.
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.
Disable oEmbed Discovery and the Embed Script
Stops your site from acting as an oEmbed provider: removes the discovery links, the embed REST route and the wp-embed script. Embedding YouTube and similar services keeps working.
Preload Key Scripts and Stylesheets by Handle
Adds preload hints for the enqueued scripts and stylesheets you name, so the browser fetches files that are discovered late (such as a slider script or icon font CSS) right at the start of the page load.
