DietPress puts your WordPress on a diet and speeds it up. It pairs a complete set of performance optimizations (the ones that used to ship in “Zero Config Performance Optimization”) with a clean, risk-based interface to disable the WordPress features you do not use. Everything is configurable, and the performance optimizations are already on by default, so you can simply activate and enjoy a faster site, or fine-tune every detail.
<blockquote>
Coming from “Zero Config Performance Optimization”? This is the same plugin, now called DietPress and fully configurable. All your previous optimizations stay active by default; you just gained a settings page and a whole new set of WordPress-diet options.
</blockquote>
By default WordPress loads functions, services and scripts that most sites do not need. They slow down loading times and consume hosting resources. DietPress lets you trim that fat and apply battle-tested performance tweaks, with a clear description of what each option does and what might break, organized by risk level so you always know what is safe.
<h3>TWO THINGS IN ONE PLUGIN</h3>
1. Performance optimizations (on by default)
<ul>
<li>Automatic Critical CSS inlined in the head (optional experimental deferral of non-critical CSS)</li>
<li>JavaScript defer parsing with smart dependency handling</li>
<li>Image loading attributes safety net: lazy loading, decoding=async and fetchpriority for images that bypass core</li>
<li>Automatic image dimensions for better CLS scores (including picture elements)</li>
<li>Resource hints: preconnect and DNS prefetch for common third-party origins</li>
<li>Theme stylesheet, critical fonts and logo preloading for a faster LCP</li>
<li>Google Fonts display=swap</li>
<li>RSS feed optimization (cache headers and item limit)</li>
<li>Server rules in .htaccess: browser caching, GZIP and Brotli compression, immutable cache headers, CORS for fonts and keep-alive (master switch plus per-feature toggles)</li>
<li>Database maintenance: daily expired-transient cleanup and safe query optimizations</li>
</ul>
2. Put WordPress on a diet (risk-based, opt-in)
<ul>
<li>Light (safe for any site): emojis, RSD/WLW tags, shortlinks, self-pingbacks, comment pagination, admin email check, and more</li>
<li>Moderate (evaluate first): oEmbed, jQuery Migrate, Dashicons on the frontend, Global Styles and Duotone, remote block patterns, avatars and Gravatar, comment threading, and more</li>
<li>Strict (site-specific): granular RSS feed control, Heartbeat API mode, post revisions and autosave, disable comments, XML sitemap, native lazy loading/fetchpriority, content types, and more</li>
<li>Widgets: dashboard widgets (including third-party ones from Yoast, WooCommerce, Elementor, Jetpack, Wordfence, Rank Math, Gravity Forms), classic sidebar widgets, block-editor widgets and the Customizer</li>
</ul>
<h3>SCALE, PROFILES AND ANALYZER</h3>
<ul>
<li>Savings indicator: HTTP requests removed, CSS/JS saved and active optimizations at a glance</li>
<li>Quick profiles: Personal Blog, WooCommerce Store, Landing Page and Maximum Cleanup</li>
<li>Site analyzer: personalized recommendations based on your active plugins and content</li>
<li>Import and export your whole configuration as a JSON file</li>
</ul>
<h3>COMPATIBILITY AND EXTENSIBILITY</h3>
The plugin includes filters for developers:
<ul>
<li><code>dietpress_critical_css</code> – Customize the inline critical CSS</li>
<li><code>dietpress_critical_css_handles</code> – Define which CSS handles are critical</li>
<li><code>dietpress_skip_defer_script_handles</code> – Opt scripts out of the JavaScript defer</li>
<li><code>dietpress_skip_defer_style_handles</code> – Opt stylesheets out of the CSS deferral</li>
<li><code>dietpress_preconnect_hints</code> – Customize preconnect origins</li>
<li><code>dietpress_dns_prefetch_domains</code> – Customize DNS prefetch domains</li>
<li><code>dietpress_critical_fonts</code> – Define critical fonts to preload</li>
</ul>
Compatible with:
<ul>
<li>Well-coded themes and page builders (Divi, Elementor, Beaver Builder, Gutenberg)</li>
<li>Cache plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, etc.)</li>
<li>Security plugins (DietPress focuses on performance and deliberately leaves security to them; we recommend our free Vigilant)</li>
<li>CDNs (Cloudflare, StackPath, KeyCDN, etc.) thanks to CORS and Vary headers</li>
<li>WordPress Multisite</li>
</ul>
<h3>HOW TO VERIFY THE OPTIMIZATIONS</h3>
<ul>
<li>Cache rules: check your <code>.htaccess</code> for a block marked <code># BEGIN DietPress</code> with <code>immutable</code> Cache-Control headers</li>
<li>Logo preload: view page source and look for <code><link rel="preload" ... fetchpriority="high"></code> pointing to your logo</li>
<li>Critical CSS: view source and look for <code><style id="core-diet-critical-css"></code> in the head</li>
<li>Compression: test at <a href="https://www.giftofspeed.com/gzip-test/" rel="nofollow ugc">giftofspeed.com/gzip-test</a></li>
</ul>
Always measure with tools like Google PageSpeed, GTMetrix or WebPageTest, and run each test at least twice to account for caching.

In-Browser Cache leverages modern browser capabilities through the Service Worker API to implement in-browser caching for static assets, improving website performance while providing transparent metrics.
Unlike traditional server-side caching plugins, In-Browser Cache operates entirely on the client-side, reducing network requests and improving page load times on repeat visits.
<h4>Key Features</h4>
<ul>
<li>In-Browser Caching: Leverages Service Workers to cache static assets directly in the browser</li>
<li>Passive CDN Recognition: Automatically detects and optimizes caching for major CDN providers (Cloudflare, BunnyCDN, Fastly, Amazon CloudFront, and more)</li>
<li>Active CDN Support: Proactively monitors CDN health and implements fallback strategies when CDN issues are detected</li>
<li>Smart Caching Strategies: Different strategies for different content types:
<ul>
<li>Cache-first for static assets (JS, CSS, images, fonts)</li>
<li>Network-first for HTML content</li>
<li>Network-only for API/dynamic routes</li>
</ul>
</li>
<li>Intelligent CDN Detection: Uses domain patterns, HTTP headers, and heuristics to identify CDN assets without configuration</li>
<li>Proactive CDN Management: Actively monitors CDN health and implements fallback strategies when CDN issues are detected</li>
<li>Simple Configuration: One-click enable/disable toggle with sensible defaults</li>
<li>Enhanced Metrics: Track cache performance separately for CDN vs origin assets</li>
<li>Visual Dashboard: See the impact of caching with clear charts and statistics including CDN performance</li>
<li>Zero Configuration: Works out of the box with sensible defaults – CDN detection is automatic</li>
<li>Performance Safeguards: Automatic cache management and minimal impact on page load</li>
<li>No External Dependencies: Everything runs on your WordPress site without external services</li>
<li>GDPR Compliance: Automatic service worker disabling for logged-in users to ensure privacy</li>
</ul>
<h4>How It Works</h4>
In-Browser Cache uses the Service Worker API to intercept network requests and apply different caching strategies:
<ol>
<li>Service Worker Registration: When a user visits your site, a service worker is registered in their browser</li>
<li>Request Interception: The service worker intercepts requests for assets</li>
<li>Passive CDN Detection: Automatically identifies CDN assets using domain patterns (Cloudflare, BunnyCDN, Fastly, CloudFront domains), HTTP headers (cf-ray, bunnycdn-cache-status, x-served-by, x-amz-cf-id), and heuristics (domains containing ‘cdn’, ‘static’, ‘assets’)</li>
<li>Active CDN Monitoring: Proactively monitors CDN health and implements fallback strategies when CDN issues are detected</li>
<li>Caching Strategy Application: Different strategies are applied based on content type and origin (CDN vs local)</li>
<li>Metrics Collection: Cache hits, misses, and bandwidth savings are tracked separately for CDN and origin assets</li>
<li>Data Synchronization: Metrics are periodically sent to your WordPress site</li>
<li>Dashboard Visualization: Data is processed and displayed in the admin dashboard with CDN vs origin breakdowns</li>
</ol>
<h4>Benefits</h4>
<ul>
<li>Faster Page Loads: Cached assets load instantly on repeat visits</li>
<li>Reduced Bandwidth Usage: Both for your server and your visitors</li>
<li>Improved User Experience: Faster page loads lead to better user experience</li>
<li>Transparent Metrics: See exactly how caching is benefiting your site</li>
<li>Complementary to Server-Side Caching: Works alongside other caching solutions</li>
<li>Enhanced CDN Reliability: Both passive detection and active monitoring ensure optimal CDN performance</li>
</ul>
<h3>Developer Information</h3>
