Local Twemoji is a WordPress plugin to serve fallback emoji images from your own site URL rather than the WordPress.org CDN.
The purpose of this plugin is to aid sites served over a CDN as browsers now cache requests on a per site basis rather than globally.
The effect of this is that the WordPress.org CDN’s splat image is treated as two different images if downloaded from site-one.example and site-two.example. You can read more about this in the Chrome post on cache partitioning.
For sites served over a CDN, downloading the image from your own URL will be quicker as it reduces the number of servers the visitor’s browser needs to connect to.
