Cache pages across devices and environments

Seraphinite Accelerator Premium combines a high-performance WordPress file cache with content and media optimization. The cache is designed for high-load conditions, while revalidation uses minimal resources. Cache data can be separated by device and environment, and cached user sessions are protected from brute-force attacks.

Supported encodings include GZip, Deflate, Compress, Brotli, and Uncompressed. Cache compression reduces storage use, and browser caching through .htaccess can reduce server load.

Remote optimization and the page-view limit

Premium can run optimization on the provider’s cloud servers. Its included allocation is 1,000 CPU seconds per hour, 10,000 per day, and 300,000 per month. Premium removes the free version’s 5,000-page-view monthly limit for optimization. After the free version reaches that limit, it continues to cache pages without optimization.

Manage page updates and website assets

Lazy revalidation keeps pages quick to serve while content is updated. Multiple CDN support lets sites balance delivery across CDNs to improve speed and reduce costs. Identical cache parts can be stored once to save space, and user-aware caching supports user-dependent pages such as shopping carts and online courses.

HTML tools check and correct unescaped scripts, misplaced tags, and lost tags. Content optimization minifies JavaScript, CSS, and HTML. Media tools can lazy-load pictures, video, frames, and fonts; scripts and styles can be lazy-loaded, inlined, or deferred.

Premium support and site presentation

The Premium edition removes the banner at the bottom of the site and promotions for related plugins. It includes three hours of personal prioritized support per site. Additional support is listed at 30 EUR per hour, and issues caused by the product are fixed free of charge.
