Custom CDN (Pro Add-on)

Route images and assets through your own CDN domain for maximum performance.

Folder Structure Requirement

Your CDN must mirror Ghost's exact folder structure. Content paths (/content/images/, /content/media/) and asset paths (/assets/built/, /assets/js/, /assets/fonts/) must be identical.

Ghost:   https://yoursite.com/content/images/2025/08/flower.png
CDN:     https://cdn.yoursite.com/content/images/2025/08/flower.png

How do I set up Custom CDN?

Enable "Custom CDN" module in the Pro generator wizard.
Enter your CDN base URL (e.g. https://cdn.yoursite.com).
(Optional) Set a separate Image CDN URL for images only.

Point your CDN origin to your Ghost domain. SnapStatic handles all URL rewriting automatically.

Which CDN providers are recommended?

Cloudflare CDN — free tier available
BunnyCDN — $1/TB, fast global PoPs
AWS CloudFront — enterprise

What gets rewritten to CDN URLs?

/content/images/, /content/media/ → CDN URL
/assets/ → CDN URL (if asset CDN is set)
HTML internal paths stay exactly the same
