## Description
Your visitors decide to stay or leave in under 3 seconds. **xSpeed** makes sure
they stay.
Most caching plugins bury you in settings, charts, and upgrade popups. xSpeed does
the opposite — install it, flip one switch, and your site loads faster. No bloat,
no upsells nagging you, no PhD required.
Built by the team at **WPDeveloper** — trusted by over 7 million WordPress users
worldwide.
#### What Does xSpeed Do?
xSpeed is a full-site performance plugin. It caches your pages, shrinks your code,
compresses your files, and serves everything as fast as your server physically can—
including an AI-powered audit that tells you exactly what’s slowing your site down.
The result: pages that load in milliseconds, not seconds. Better Google PageSpeed
scores. Happier visitors. Better SEO rankings.
#### The Speed Advantage No Other Free Plugin Offers
When xSpeed caches a page, it doesn’t just save it — it serves it directly from
the server, bypassing PHP entirely.
That means:
* **With xSpeed static cache:** 5–15ms response time
* **Without it (PHP-served cache):** ~85ms response time
That’s up to **17× faster** page delivery on cache hits. No other free caching plugin
does this across Apache, nginx, and LiteSpeed automatically.
#### Features at a Glance
**Page Caching**
Your pages are saved as static HTML files and served instantly to visitors — before
WordPress even loads. The cache rebuilds itself automatically whenever you publish
a post, switch themes, or update a plugin. You never have to think about it.
* Static-file rewrite path (bypasses PHP entirely — 5–15ms TTFB)
* Auto-purge on publish, update, comment, theme change
* One-click cache purge from the admin bar
* Exclude specific URLs (e.g. `/cart`, `/checkout`, `/my-account`)
* Set your own cache expiry (1–720 hours)
* Separate mobile cache for phone and tablet visitors
* Per-post cache rules — custom expiry or disable caching for individual posts
**Code Minification**
Strips all the unnecessary whitespace, comments, and characters from your HTML,
CSS, and JavaScript without breaking anything.
* Minify HTML, CSS, and JavaScript
* Combine CSS and JS files to reduce HTTP requests
* Defer or delay JavaScript so it doesn’t block page rendering
* Async CSS loading
* Removes `?ver=` query strings from asset URLs
* Safe-minify: automatically skips already-minified files and falls back if anything
looks off
**GZIP Compression**
Makes every file your server sends smaller — so browsers download them faster.
* Auto-configures GZIP on Apache and LiteSpeed
* Shows a ready-to-paste config snippet for nginx and IIS
* Detects if your server already has GZIP active — no double-configuration
**Lazy Load**
Images, videos, and iframes load only when a visitor scrolls to them — not all at
once on page load.
* Lazy load images, iframes, and videos
* Automatic CLS (Cumulative Layout Shift) fix so your layout doesn’t jump
**Fonts Optimization**
Web fonts are one of the most common causes of slow-loading pages.
* Adds `font-display: swap` so text is visible immediately while fonts load
* Preloads above-the-fold font files for instant rendering
* Removes the blank-text flash caused by slow Google Fonts responses
**Browser Cache**
Tells browsers to remember your static files (images, CSS, JS) so returning visitors
load your site even faster.
* Sets proper `Cache-Control` and `Expires` headers
* Works automatically — no manual configuration needed
**Cache Preloader**
Warms up your cache automatically so the very first visitor after a purge still
gets a fast page.
* Sitemap-driven cache warmer
* Auto-warms cache when you publish or update content
**Object Cache (Redis / Memcached)**
Speed up database-heavy WordPress installs with server-side object caching.
* Connect Redis or Memcached in seconds
* View status and flush cache from the dashboard
**CDN Support**
Serve your static files from a CDN for faster global delivery.
* Pull-zone URL rewriting for any CDN provider
* Built-in Cloudflare integration: connect your zone, auto-purge on publish, toggle
dev mode
**Database Optimization**
A bloated database slows down every page load. xSpeed keeps yours clean.
* Optimize database tables
* Remove post revisions, spam, trash, transients, and orphaned meta
* Schedule automatic cleanup so it runs on autopilot
**Disable Bloat**
Turn off WordPress features you don’t use — each one is a request your server doesn’t
have to make.
* Disable dashicons on the frontend
* Remove oEmbed, RSS feeds, XML-RPC, jQuery Migrate, REST API authentication headers
**AI-Powered Site Audit (Pro)**
xSpeed Pro scans your specific site and tells you exactly which performance features
will help the most — with severity ratings and concrete reasons, not generic advice.
#### Smart Enough to Stay Out of Trouble
xSpeed handles the edge cases other plugins miss:
* **Multisite ready** — each site in the network gets its own cache and settings.
* **LiteSpeed server?** — xSpeed detects LiteSpeed Cache’s server module and steps
back to avoid conflicts.
* **WooCommerce?** — logged-in customers and checkout pages are never cached.
* **WordPress Site Health** — xSpeed adds its own health check under Tools Site
Health so you always know your cache config is working correctly.
* **Works on any server** — Apache, nginx, LiteSpeed, IIS, and any standard PHP
host.
#### Designed for Everyone
**Non-technical users:** A 3-step setup wizard walks you through first-time configuration
in under 2 minutes. Settings auto-save — there’s no Save button to forget.
**Developers:** REST API at `/wp-json/xspeed/v1/`, developer filters (`xspeed_skip_minify`,`
xspeed_cache_skip_for_post`, `xspeed_cache_expiry_for_post`), `WP_DEBUG` awareness,
and a React 18 + TypeScript admin UI under 80 KB gzipped.
**Agencies:** Use the `xspeed_branding` filter to white-label the dashboard for
clients.
#### Completely Private
xSpeed never collects personal data, stores IP addresses, uses tracking cookies,
or contacts any third-party server. Every optimization runs locally on your server.
The only external request it makes is a quick check to your own site’s home URL
to confirm GZIP is active — and even that is rate-limited to once per hour. (See“
External services” below.)
#### Backed By a Team You Trust
xSpeed is developed by the trusted team at WPDeveloper, a leading WordPress marketplace
used and loved by millions of users.
#### Loved xSpeed?
If xSpeed makes your site faster, please leave a review on WordPress.org — it really
helps!
### 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 site’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.

## Installation
1. Go to **Plugins Add New** in your WordPress admin and search for **xSpeed**.
2. Click **Install Now**, then **Activate**.
3. Navigate to **xSpeed** in your sidebar.
4. The setup wizard will guide you through the rest — it takes about 2 minutes.
That’s it. Your site is now faster.
## FAQ
### Will this break my site?
Very unlikely. xSpeed includes safety checks for every optimization: minification
falls back to the original if anything looks off, and the cache bypasses logged-
in users, admin pages, AJAX, and REST requests automatically. If something ever
looks wrong, you can toggle any feature off individually.
### Does it work with WooCommerce?
Yes. Add `/cart`, `/checkout`, and `/my-account` to the Excluded URLs list and xSpeed
will skip caching those pages. Logged-in customers are never served cached pages
regardless.
### Does it work with my server?
xSpeed works on Apache, nginx, LiteSpeed, IIS, and any standard PHP host. Static-
cache rewriting and GZIP auto-configuration work out of the box on Apache and LiteSpeed.
For nginx and IIS, xSpeed shows you a ready-to-paste config snippet.
### Does it support WordPress Multisite?
Yes. Each site in the network has its own independent cache and settings.
### Will it conflict with LiteSpeed Cache?
No. xSpeed detects LiteSpeed’s server-level caching module and steps back automatically
to avoid double-caching. Otherwise, only run one page-cache plugin at a time.
### How do I exclude a page from being cached?
Go to **xSpeed Settings**, paste the URL path (e.g. `/cart`) into the Excluded
URLs field — one path per line. Changes save automatically.
### How do I clear the cache?
Click **Purge** in the xSpeed dashboard, or use **Purge xSpeed Cache** in your admin
bar. The cache also clears itself automatically whenever you publish or update content.
### Can I use xSpeed alongside Cloudflare?
Yes. The built-in Cloudflare module connects your zone and auto-purges Cloudflare’s
cache whenever xSpeed purges its own — so both caches stay in sync.
### Can I disable minification temporarily for debugging?
Yes. Either toggle the option off in the admin UI, enable `WP_DEBUG` (xSpeed automatically
skips HTML minification when debug is on), or use the `xspeed_skip_minify` filter.

## Changelog
#### [1.0.3] – 2026-06-09
**Topology-aware UX, nginx HIT counting, admin polish.**
Cache topology & UX:
– New: Topology-aware rewrite banner — the dashboard now detects
containerized hosts (xclude, Kinsta, RunCloud Atomic, etc.) where the `$document_root`
assumption doesn’t hold, and tells the user exactly what to expect on their stack
instead of silently failing. – New: Unified nginx server-block snippet — one consolidated,
copy-pasteable snippet (collapsible in the UI) replaces the previous fragmented
sections. – New: Nginx-served HITs are now counted — a dedicated access_log captures
cache hits served directly by nginx (no PHP), so the dashboard “HITs in last 24h”
stat is accurate on nginx setups. – New: `X-XSpeed-Cache` response header — cache
hits are now visible in the response headers, with a distinct value per serve layer(`
HIT (nginx)` for the fast static path, `HIT (php)` for the drop-in fallback) so
you can confirm a page was cached and tell exactly which layer served it. – Improved:
Browser Cache notice is topology-aware and renders its snippet in a proper code
block.
Admin UX:
– New: Third-party admin notices are suppressed on xSpeed admin screens(`
page=xspeed*` only) — other plugins’ “rate us” / promo notices no longer crowd the
xSpeed dashboard. – New: Aligned sticky title-bar across the sidebar and content
panels for a cleaner scroll experience. – Improved: Browser Cache + GZIP notices
probe-gate themselves — once the underlying issue is resolved, the notice dismisses
on its own instead of lingering.
Benchmark:
– Fixed: “Without cache” leg of the dashboard speed test now appends
a cache-buster query string. Previously it was hitting the cache and reporting an
artificially-fast baseline, making the speedup number look small.
#### [1.0.2] – 2026-06-02
**Static-rewrite cache, Site Health & Fonts.**
Static-rewrite cache + Site Health:
– New: Static-file rewrite path — cached HTML
is served directly by Apache / nginx / LiteSpeed, bypassing PHP entirely on cache
hits (5-15ms TTFB vs ~85ms via the PHP drop-in). – New: .htaccess static-cache block—
installed automatically on cache enable, removed cleanly on disable. Block precedes
WordPress’s own rules so static files match first. – New: nginx config snippet —
copy-pasteable server { } block surfaced in the dashboard when nginx is detected(
PHP can’t write nginx config). Avoids the “if is evil” pitfall via a named-location
fallback. – New: LiteSpeed LSCache coexistence — xSpeed detects LSCache’s server-
level module and steps back instead of double-caching. – New: Active rewrite probe—
Health module pings the cache directory and confirms the rewrite is actually serving
static bytes (not just present in .htaccess). – New: WordPress Site Health integration—
Tools Site Health now lists an xSpeed check covering static-rewrite status + nginx
config requirements. – New: Persistent banner — Cache panel warns the admin when
caching is on but the static-rewrite block isn’t engaged (slow fallback path). –
New: Copy-to-clipboard button on every config-snippet panel (nginx, GZIP, object-
cache).
Fonts:
– New: Fonts module — adds `font-display: swap` to enqueued web fonts so
visible text doesn’t wait on a slow Google Fonts response, and exposes a preload
list for above-the-fold font files. – New: FontsModule tests covering the swap rewrite
+ preload `` emission.
Improvements & fixes:
– Improved: Server-type detection is cached so CLI / cron
contexts see the same server type as web requests. – Improved: Drop-in (advanced-
cache.php) and WP_CACHE constant are preserved across plugin upgrades; auto-heal
hook tightened to admin_init to avoid REST/cron noise. – Improved: Plugin Check
pass — i18n textdomains, WP_Filesystem coverage, SQL preparation, sanitization,
and plugin/readme headers all cleaned up for WordPress.org review. – Fixed: nginx
snippet rewritten to avoid the try_files trap that broke pretty permalinks. – Fixed:
Rewrite condition normalized for trailing-slash + non-trailing-slash URLs. – Fixed:
WP-Rocket-style canonical pattern — server-level conditional rewrite. – Fixed: Minify
tag-rewrite filters bail in non-frontend contexts (REST / admin / cron). – Fixed:
wp.org release zip now ships `vendor/` — resolves the 1.0.1 activation fatal. –
Improved: Release pipeline rebuilt — `.distignore`-driven dist build, CI verify
step, version-named artifact on every run. – Improved: Plugin version read from
the PHP header — single source of truth.
#### [1.0.1] – 2026-06-01
**Foundation release — full feature set + Pro hooks.**
Module architecture + LiteSpeed parity floor:
– New: Module architecture — every
feature now ships as a self-contained Module (Cache, Health, Preloader, Heartbeat,
Minify, GZIP, Lazy Load, Disable Bloat, Database, CDN, Cloudflare, Object Cache,
Browser Cache). – New: Health module — 24-hour hit/miss counter + activity log. –
New: Preloader module — sitemap-driven cache warmer with content-publish auto-warm.–
New: Cache exclusion intelligence — glob URL patterns, cookie patterns, User-Agent
bypass, ignored query parameters. – New: Per-device cache (mobile-separate). – New:
Per-post cache rules — don’t-cache + custom expiry meta box. – New: Minification—
CSS / JS / HTML minify, combine, defer JS, delay JS, async CSS, remove ?ver= query
strings. – New: Lazy Load module — images / iframes / videos + auto CLS-fix. – New:
Disable Bloat module — 6 ergonomic toggles (dashicons, oEmbed, RSS, XML-RPC, jQuery
Migrate, REST auth). – New: Database module — optimize tables, scheduled cleanup,
autoload analysis. – New: CDN module — pull-zone URL rewriting. – New: Cloudflare
module — zone connect, auto-purge, dev-mode toggle. – New: Object Cache module —
Redis / Memcached config + status + flush. – New: Browser Cache module — Cache-Control
+ Expires headers. – New: Settings search across the entire dashboard with keyword
highlighting. – New: 3-step setup wizard on first activation with preset chooser
and benchmark. – New: Sidebar grouping under domain headers (Cache / Performance/
Network / Insights / Tools). – New: Sidebar tooltips + search shortcut in the collapsed
rail. – New: xspeed_branding filter — agencies can rebrand the dashboard. – New:
xspeed_cache_skip_for_post + xspeed_cache_expiry_for_post filters.
Pro-essentials (everything xSpeed Pro depends on, bundled here so any Pro release
works against this single Free version):
– New: xspeed_module_descriptor filter—
Pro hooks this to swap its panels to LicenseLockedPanel when license is invalid.–
New: AI Privacy module — GDPR off-switch + xspeed_ai_can_collect_data filter that
Pro AI features must consult before recording visitor data. – New: Pro upsell teasers—
in-context inline cards on Cache, Minify, Lazy Load, Browser Cache and Disable Bloat
panels. – New: Locked Pro module rows in the sidebar — shows what Pro offers with
a clear upgrade prompt. – New: Pro Audit on the Cache panel — site-specific scan
listing the top Pro features that would help THIS site, with severity chips and
concrete reasons (not generic marketing copy). – New: Sidebar slot for the license
module (appears when xSpeed Pro is installed). – New: Global 36px form-control height
baseline across the dashboard. – New: filemtime() cache busting on admin asset URLs.
Improvements & fixes:
– Improved: React panel registry — modules auto-render in
the dashboard. – Improved: Portal-based save indicator — zero layout shift. – Improved:
Distribution zip prunes dev dependencies (composer install –no-dev). – Fixed: 5
duplicate module icons + regression test.
