Speed Without the Bloat

Most caching plugins ship with hundreds of options, dashboards full of charts, and constant upsell prompts. xSpeed takes the opposite approach: a single-page admin UI, a master toggle, and the optimizations that move the needle. Activate, flip the switch, done.

xSpeed delivers full-page caching, HTML/CSS/JS minification, and GZIP compression in a clean React-powered admin built for developers and site owners who want speed without the noise.

Key Features

Page Caching

• Full-page static HTML caching for non-logged-in visitors.
• Drop-in (advanced-cache.php) serves cached responses before WordPress fully boots — minimal PHP overhead per request.
• Automatic cache invalidation on post publish/update, comment activity, theme switch, and plugin activation/deactivation.
• Honors the DONOTCACHEPAGE constant.
• Bypasses cache for admin, AJAX, REST, cron, POST requests, and logged-in users.
• Configurable cache expiry (1–720 hours, default 24).
• URL-based exclusions (one path per line — useful for /cart, /checkout, /my-account).
• One-click purge from the admin bar or settings page.

Code Minification

• HTML minification — strips whitespace and comments while preserving <pre>, <textarea>, <script>, and <style> content.
• CSS minification — local enqueued stylesheets are minified once, cached on disk, and the loader URL is rewritten transparently.
• JavaScript minification — same flow as CSS; safely skips already-minified bundles and validates output to prevent breakage.
• Powered by matthiasmullie/minify for production-grade compression.
• xspeed_skip_minify filter for fine-grained control.

GZIP Compression

• Apache and LiteSpeed: auto-configures .htaccess with mod_deflate rules.
• Nginx, IIS, or other servers: surfaces a copy-pasteable snippet for the userÌtumọ̀ Yorùbá: ’s server config.
• Detects whether the server already serves gzipped responses and shows an “Active on server” indicator.

Built for Developers

• Single-page admin UI built with React 18 + TypeScript + Tailwind CSS.
• Light and dark mode with persistent preference (defaults to light).
• Collapsible sidebar that remembers state across sessions.
• Auto-save settings — no Save button.
• REST API at /wp-json/xspeed/v1/ for programmatic control.
• Initial settings bootstrapped into the page — zero loading state on first render.
• Bundle size under 80 KB gzipped.

Cross-Server

• Works on Apache, nginx, LiteSpeed, IIS, and any PHP-capable host.
• Server-specific behavior (where applicable) is handled gracefully — no silent failures.

Perfect For

• Content-heavy blogs and news outlets.
• Small-to-mid WooCommerce stores.
• Business and portfolio sites.
• Developers who want a clean, no-noise caching plugin.

Privacy

xSpeed is designed with privacy in mind. The plugin does not collect personal user data, store IP addresses, use tracking cookies, or contact any third-party servers. All optimizations happen locally on your server. The only HTTP request xSpeed ever makes is to your own siteÌtumọ̀ Yorùbá: ’s home URL (see “External services” below) to confirm whether your server is serving gzipped responses.

Backed By a Team You Trust

xSpeed is developed by the trusted team at WPDeveloper, a leading WordPress marketplace used and loved by over 5 million users.

External services

xSpeed contacts exactly one external endpoint, and only your own site:

Self-hosted gzip probe

• What it does: Issues a single GET request to your siteÌtumọ̀ Yorùbá: ’s home URL (home_url('/')) with an Accept-Encoding: gzip header to detect whether your web server is already serving gzipped responses. The response body is discarded; only the Content-Encoding header is read.
• When it runs: On demand when the admin dashboard loads server status, throttled to once per hour via a transient (xspeed_gzip_active).
• Where the request goes: Your own site (home_url()). xSpeed does not contact any third-party server, analytics endpoint, license server, or telemetry collector.
• What is sent: No personal data, no site identifiers, no payload — just a standard HTTP GET from your server back to your server.
