Short answer: The best WordPress cache plugins in 2026 are, from #1: WP Rocket, LiteSpeed Cache, W3 Total Cache, FlyingPress, WP Super Cache, Cloudflare, Breeze, Proxy Cache Purge, Nginx Helper and WP Fastest Cache. Use only one page cache at a time, and purge it after every design or content change so visitors see the latest version.
Caching saves a ready-made copy of each page, so WordPress does not rebuild it for every visitor. As a result, WordPress cache plugins are the quickest way to speed up a site. However, a cache can also show visitors an old version until you purge it. So for each tool below we explain what it does, whether it is free, and how to clear its cache.
Key takeaways
- #1 WP Rocket is the easiest; #2 LiteSpeed Cache is best on LiteSpeed servers.
- Use one page-cache plugin, plus a purge helper for your host or CDN if needed.
- Purge after changing design, menus, prices or templates.
- Check whether your host already caches pages for you.

How to purge cache in WordPress cache plugins
- First, use your cache plugin’s Clear cache or Purge all button in the admin bar.
- Then purge your host or CDN cache, for example Cloudflare.
- Next, open the page in a private window to skip your browser cache.
- Finally, check the page on a phone, because mobile pages can have their own cache.
Also, purge after updating your theme, menus, prices or page builder templates. For instance, the Attestra Solutions theme asks you to purge the cache after every update for exactly this reason.

Frequently asked questions
QCan I use two WordPress cache plugins together?
No. Two page caches fight each other and cause errors. Instead, use one page cache, plus a purge helper for your host or CDN if needed.
QWhy do I still see the old version after updating?
Because a cache still holds the old copy. Purge the plugin cache, then your host or CDN cache, and finally your browser cache.
QDo WordPress cache plugins work with WooCommerce?
Yes. Good cache plugins automatically skip the cart, checkout and account pages, so shoppers always see live data.
