LiteSpeed Cache vs Redis Object Cache (2026): PluginCheck
Quick Verdict
Pick LiteSpeed Cache if you want a single all-in-one plugin that handles page, browser, and asset optimization with zero server config. Pick Redis Object Cache if your hosting already runs Redis and your site is bottlenecked by repeated database queries, especially dynamic WooCommerce or membership sites.
Both LiteSpeed Cache and Redis Object Cache target site speed, but they solve performance at very different layers. Choosing between them usually comes down to whether your bottleneck is page delivery (HTML, CSS, JS, images) or backend database queries. Stack-wise, these plugins are not mutually exclusive, but most sites only run one caching strategy at the top level.

Where LiteSpeed Cache Wins
Massive user base and trust
LiteSpeed Cache has 7 million active installs versus 400,000 for Redis Object Cache, a 17x difference that signals broader real-world testing and lower risk of edge-case bugs.
Higher rating density
It scores 96/100 from 2,759 ratings, far more reliable than Redis Object Cache's 90/100 from only 175 ratings where smaller samples are easier to skew.
All-in-one feature set
LiteSpeed Cache bundles page caching, image optimization, CSS/JS minification, and critical CSS generation, while Redis Object Cache only handles object caching and leaves everything else to other plugins.
Where Redis Object Cache Wins
Much better support resolution
Redis Object Cache resolves 90.9% of support threads versus 69.6% for LiteSpeed Cache, a meaningful gap if you hit configuration problems during setup.
More recent maintenance signal
It was updated on 2026-05-04, about a month after LiteSpeed Cache's 2026-04-01 update, and both earn a perfect 100/25 on maintenance so neither is stale.
Cleaner, single-purpose scope
By focusing only on persistent object caching with Predis, PhpRedis, Relay, replication, and clustering, it does one thing well instead of juggling 10 optimization modules.
Score-by-Score Comparison
LiteSpeed Cache dominates with 100/30 versus 84/30, reflecting its 7M installs and far larger community footprint.
Both plugins score a perfect 100/25 here, with updates within the last six weeks and active development on each side.
LiteSpeed Cache edges ahead at 96/15 versus 90/15, and the gap is reinforced by a much larger and therefore more trustworthy rating sample.
Redis Object Cache wins this dimension at 91/15 versus 70/15, with a 90.9% resolution rate compared to 69.6%.
Both score 100/15 on compatibility, requiring standard PHP 7+ and working across the major WordPress versions without issues.
The Bottom Line
For the typical WordPress site owner, LiteSpeed Cache is the safer and more impactful pick: it scores 94.84/100 overall, has 7 million active installs, a 96/100 rating across nearly 2,800 reviews, and bundles every optimization layer in one plugin. Redis Object Cache scores a respectable 92.22/100 and wins on support, but it only addresses database query caching and assumes you already have Redis configured on your server. Unless you specifically need persistent object caching for a high-query dynamic site, LiteSpeed Cache will deliver more speed improvement with less setup work.
