FlyingPress can automatically download and serve key external CSS and JavaScript files locally to improve loading speed and reliability.
How it works
When enabled:
FlyingPress detects supported third-party resources (like CSS/JS libraries) loaded from known CDN domains
These files are downloaded and served from your own site’s domain
This avoids external DNS lookups and improves caching by browser and CDN
Benefits
Faster load times by eliminating external requests
Improves PageSpeed and Core Web Vitals scores
Reduces reliance on third-party networks
Keeps critical styles and scripts always available
This is especially useful when using popular libraries like Bootstrap, Font Awesome, or jQuery from external CDNs.
Default supported domains
FlyingPress automatically self-hosts assets from the following domains:
cdn.jsdelivr.net
cdnjs.cloudflare.com
unpkg.com
code.jquery.com
ajax.googleapis.com
use.fontawesome.com
bootstrapcdn.com
cdn.rawgit.com
Customizing domains
You can add or modify the list of self-hosted domains using a filter.
