The strongest Redis Object Cache alternative for most sites is LiteSpeed Cache, an all-in-one caching suite that adds page caching, optimisation, and object caching well beyond Redis alone. For a full free caching plugin on any host, W3 Total Cache is the most complete pick, while Docket Cache is the standout if you want faster object caching without running a Redis server. We ranked these from our index of 55,000+ WordPress plugins.

Why people switch from Redis Object Cache

• Redis Object Cache only handles object caching, so sites wanting page caching and optimisation too move to LiteSpeed Cache or W3 Total Cache.
• It needs a running Redis server, so people without one move to file-based Docket Cache or Object Cache 4 Everyone.
• Sites on managed hosting wanting a lean, battle-tested Redis integration move to WP Redis.
• Those on LiteSpeed servers wanting the fastest all-round result move to LiteSpeed Cache.

LiteSpeed Cache – All-in-one caching suite

LiteSpeed Cache, by LiteSpeed Technologies, is a complete caching and optimisation suite covering page cache, CSS and JS minification, image optimisation, and object caching. Against Redis Object Cache, it addresses full-page performance rather than object caching alone. What it does not do: its most powerful server-level page caching needs a LiteSpeed or OpenLiteSpeed server, so on other hosts you lose some of its edge.

Choose LiteSpeed Cache if you want an all-in-one caching suite, ideally on LiteSpeed.

W3 Total Cache – Full stack, any host

W3 Total Cache, by BoldGrid, is a long-established caching plugin offering page, object, database, and browser caching with CDN support, and it can use Redis or Memcached as a backend. Against Redis Object Cache, it bundles many caching layers in one plugin. What it does not do: it exposes a lot of settings, so it is easy to misconfigure and can feel complex for beginners.

Choose W3 Total Cache if you want a full caching stack that works on any host.

WP Redis – Lean Redis backend

WP Redis, maintained by Pantheon, is a lean object cache backend that connects WordPress to Redis with a focus on reliability at scale. Against Redis Object Cache, it is deliberately minimal and battle-tested on high-traffic managed hosting. What it does not do: it offers little in the way of a settings interface or diagnostics, so it assumes you manage Redis yourself.

Choose WP Redis if you want a minimal, proven Redis object cache backend.

Docket Cache – Object cache, no server

Docket Cache is a persistent object cache that stores data as PHP files on disk, so it speeds up object caching without needing Redis or Memcached installed. Against Redis Object Cache, it removes the requirement to run and maintain a separate cache server. What it does not do: file-based caching is generally slower than an in-memory store like Redis at very high load.

Choose Docket Cache if you want persistent object caching without a Redis server.

Object Cache 4 Everyone – Simplest object caching

Object Cache 4 Everyone is a simple plugin that enables object caching using Redis or Memcached with minimal configuration. Against Redis Object Cache, it aims to make turning on object caching as easy as possible. What it does not do: it is a lightly maintained, basic tool, so it lacks the diagnostics and polish of more actively developed object cache plugins.

Choose Object Cache 4 Everyone if you want the simplest way to switch object caching on.

When to stay on Redis Object Cache

Stay on Redis Object Cache if you already run a Redis server and want a focused, well-maintained object cache and nothing more. It is one of the cleanest Redis integrations available, with a clear dashboard and reliable performance. If a separate page cache or CDN already handles the rest of your stack, adding a full caching suite would only duplicate work.

How we ranked these

Every plugin here is scored by the WPS Score, a single 0 to 10 rating built from 21 signals covering maintenance, support responsiveness, compatibility, performance, and ratings quality across our index of 55,000+ plugins. Rankings are derived from that data, not editorial preference, and no plugin author can pay to change a score. How the WPS Score works.

Frequently asked questions

What is the difference between Redis Object Cache and LiteSpeed Cache?

Redis Object Cache handles object caching, storing database query results in Redis to reduce load. LiteSpeed Cache is a full suite that adds page caching, minification, and image optimisation, and includes object caching too. They solve related but different problems, and some sites run a page cache alongside a dedicated object cache.

Do I need a Redis server to use object caching?

Not always. Redis Object Cache and WP Redis require a running Redis server, but alternatives like Docket Cache use disk-based PHP files instead, so you can get persistent object caching without installing Redis. In-memory options like Redis are usually faster under heavy load, however.

What is the best free alternative to Redis Object Cache?

LiteSpeed Cache and W3 Total Cache are the best free alternatives if you want full caching rather than object caching alone. LiteSpeed Cache is especially strong on LiteSpeed servers, while W3 Total Cache works on any host and can still use Redis as its object cache backend.

The verdict

The best all-round Redis Object Cache alternative is LiteSpeed Cache for combining page and object caching in one suite, with W3 Total Cache winning as a host-agnostic caching stack and Docket Cache for object caching without a Redis server. If you run Redis and only need object caching, staying on Redis Object Cache is entirely valid.
