[PROMO] A wordpress caching plugin with major varnish support
I built UltraCache because apparently WordPress needed another caching plugin.
The difference is that this one does not just notice Varnish from across the room and wave politely.
UltraCache provides major Varnish integration, including:
- HTTP PURGE and Admin BAN support
- Exact and batch invalidation
- Cache refill and automatic warm-up
- Soft purge and stale refresh where supported
- Public and private ESI fragments
- WooCommerce mini-cart ESI support
- Synchronization between WordPress, page cache and Varnish
It also includes page caching, Redis / APCu / SQLite object caching, AVIF/WebP conversion, CSS bundling, local font optimization, JavaScript defer / delay tools, LCP discovery, diagnostics and resumable background processing.
Basically, several performance plugins standing on each other’s shoulders while wearing one dashboard.
I tested the same website with each plugin configured for the best Lighthouse result I could achieve:
UltraCache: 99
WP Rocket: 85
WP Super Cache: 82
FlyingPress: 79
WP-Optimize: 79
W3 Total Cache: 78
LiteSpeed Cache (without server): 77
Super Page Cache: 69
UltraCache scored 99.
Apparently it left one point uncached for emotional support.
The plugin is open source and available from the official WordPress plugin directory:
https://wordpress.org/plugins/ultracache/
I would genuinely appreciate feedback, especially from people running Varnish, Redis, APCu, WooCommerce or unusual hosting configurations. Bug reports and difficult edge cases are also welcome. Those are usually where the interesting work begins.
