Included free with Zinn Digital® hosting
Every WordPress site on our own servers comes with Zinn® Cache installed and connected: the page cache is on, the Redis object cache is managed for you, and plugin updates arrive on their own. Zinn® Cache Pro is not included; add it to any site when you want it.

Hosting customers get a personal code for 50% off their first payment of every Zinn® Pro plugin, straight from their dashboard.
