Improve the user experience of your website
Pages served as ready-made files load in milliseconds, which lowers the bounce rate. Visitors feel the difference and browse more.
Keep a WordPress with many records in the database fast
A cached page needs no database queries at all, so sites with thousands of posts, products or comments stay quick and the database is left free for everything else.
Avoid delays from long or slow queries
Pages built from complex queries, such as filters, related posts or custom fields, are generated once and then served as files, without running those queries again for every visitor.
Speed up a WordPress with a heavy and complex theme
Page builders and feature-rich themes take a long time to render. Flash Cache renders the page once, serves the result, and combines styles and scripts into shared files, so each page makes fewer requests.
Benefit your SEO and the people searching your site
Search engine bots get the same instant answer as visitors, so crawling is faster, and loading speed, which search engines take into account, improves.
Keep ads and statistics working
Scripts from other domains stay on their own servers, so ads and analytics keep running and counting as they should while the rest of the page is served from the cache.
Make your site much harder to attack
A cached page is a plain HTML file: no PHP and no database are involved when it is served. That leaves far less exposed than WordPress running on every request, and traffic floods or brute-force attempts on cached pages are answered by the web server instead of overloading WordPress.
Fix PageSpeed and loading speed issues
Server response time, compression, combined styles and scripts and browser cache times are the points PageSpeed Insights and Core Web Vitals check. Flash Cache takes care of them.
Easy and fast for novice and advanced users
Install it, switch it on and it works, with ready-made patterns and simple screens. Advanced users can fine-tune every pattern, time and optimization.
Survive traffic spikes
A post shared on social media, a newsletter or a mention in the press brings thousands of visitors at once. Cached pages are served by the web server itself, so the spike does not use up your PHP workers.
Get more from shared hosting and small servers
Serving files takes a fraction of the CPU and memory that building a page does, so a modest plan can handle many more visitors.
Publish in bulk without slowing the site down
Importing posts, for example with WPeMatico, rebuilds each new page in the background and refreshes the home page and archives once per batch, so visitors and editors never wait.
Serve members and editors their own content
Pages are cached for visitors, while logged-in users always get the live site, so members, customers and editors see their own content.
Run it on Apache, nginx, LiteSpeed or OpenLiteSpeed
Ready-made rules and status checks for the four servers, including sites installed in a subfolder and addresses with accents or non-Latin letters.
Change your design without cold caches
Save a widget, menu, Customizer setting or block theme template and the cache refreshes by itself. On large sites pages are replaced a few at a time, so visitors never meet an empty cache.
Manage sites with thousands of pages
Emptying the cache is instant at any size, and the statistics on General Settings show how many pages, styles and scripts are cached and how much space they use.
Get the most from your marketing campaigns
Visits that carry tracking parameters such as utm_*, fbclid or gclid share the same cached page, so every campaign link is fast.
Keep live parts live with Flash Cache Pro
Mark a block or widget as “Disable cache” for counters, lists of paid links or any content that must be fresh on every visit, while the rest of the page stays cached.
