LiteSpeed Cache or Zinn® Cache?
LiteSpeed Cache is built around LiteSpeed servers and QUIC.cloud. Zinn® Cache uses LiteSpeed's cache where it exists and its own file cache everywhere else. Which to choose.
The short answer
LiteSpeed Cache needs a LiteSpeed server or the QUIC.cloud CDN for its page cache. Zinn® Cache uses LiteSpeed's cache when it is there and its own file cache when it is not — so it keeps working if you change host.
| Zinn® Cache | LiteSpeed Cache | |
|---|---|---|
| Price | Free; Pro add-on from an annual licence | Free[1] |
| Free version | Yes | Yes[1] |
| Server needed for its page cache | Any server: LiteSpeed's cache or a file cache | LiteSpeed, OpenLiteSpeed or QUIC.cloud CDN[1] |
| Object cache | Redis; Pro adds an APCu tier | Memcached, LSMCD or Redis[1] |
| Optional third-party online services | None in the cache; Freemius for Pro's licence | QUIC.cloud CDN, image optimisation and critical CSS[1] |

Why people choose Zinn® Cache over LiteSpeed Cache
No outside service: nothing about your pages is sent to a third-party server for processing.
A short, plain settings screen in 57 languages instead of hundreds of options.
Where it is the better choice
LiteSpeed Cache is maintained by LiteSpeed Technologies and used on millions of sites, and its QUIC.cloud services add image optimisation, generated critical CSS and a CDN. On a LiteSpeed server with those services in mind, it is the natural choice.
Where Zinn® Cache fits
Zinn® Cache is smaller and connects to no third-party service. It drives LiteSpeed's cache when the server has one and falls back to its own file cache when it does not, so a site can move hosts without changing plugins.
How to switch from LiteSpeed Cache in three steps
Install Zinn® Cache, keep it switched off
Add the free plugin from your WordPress dashboard. Before you turn it on, note which pages LiteSpeed Cache leaves uncached — cart, checkout, account pages — so you can check they stay uncached after the move.
Deactivate LiteSpeed Cache, then turn Zinn® Cache on
Never run two page caches at once. Deactivate LiteSpeed Cache first, then switch Zinn® Cache on. Shop and signed-in visitors are left out of the cache by default.
Check it is working
Open your site in a private window and reload: the status panel shows which page cache is in use, and the guide on checking your cache shows how to read the response headers. Then delete LiteSpeed Cache for good.
Questions about switching from LiteSpeed Cache
Can I run Zinn® Cache and LiteSpeed Cache together?
Not as two page caches — two caches storing the same page fight each other and make problems hard to find. Deactivate LiteSpeed Cache before you switch Zinn® Cache on.
Is Zinn® Cache really free?
Yes. The page cache, tag-based purging, the Redis object cache and shop-safe exclusions are free for good, with no licence key. Zinn® Cache Pro is an optional add-on from $49 a year, with a free trial and no card needed.
Will my site be faster than with LiteSpeed Cache?
Any good page cache makes the biggest difference: on our own measured test a cached page started arriving in 40 ms instead of 107 ms. How Zinn® Cache compares with LiteSpeed Cache on your site depends on your host and theme, so measure before and after — the benchmark page shows how.
