Snippet Library
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.
Holds back the scripts you list (chat widgets, heatmaps, social widgets) until the visitor first scrolls, taps, clicks or presses a key, or after a timeout, so they no longer slow down the initial page load.
Loads the stylesheets you choose in the background so they no longer delay the first paint, ideal for CSS of things below the fold like sliders or forms.
