FlyingPress is compatible with Varnish, but in most cases, Varnish is not required when FlyingPress is active.
Automatic Varnish purging
FlyingPress can automatically purge Varnish cache on:
Cloudways (fully supported out of the box)
No setup needed—caching is kept in sync after content updates
Other hosting providers
If you're using Varnish on a host other than Cloudways, we recommend:
Disabling Varnish, as FlyingPress already performs full-page caching
FlyingPress serves static HTML files directly, bypassing PHP and the database
Using Varnish in parallel may cause cache conflict, delayed updates, or double caching
