Self-Host External CSS and JavaScript

Updated this week

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.
