StaticDelivr vs DietPress

StaticDelivr CDN is a lightweight and powerful plugin designed to improve your WordPress site’s performance. By rewriting theme, plugin, core file resource URLs, optimizing images, and proxying Google Fonts through the StaticDelivr CDN, the plugin ensures faster loading times, reduced server load, better privacy, and an improved user experience. StaticDelivr is a global content delivery network (CDN) that supports delivering assets from various platforms like npm, GitHub, and WordPress. By leveraging geographically distributed servers, StaticDelivr optimizes the delivery of your static assets such as CSS, JavaScript, images, and fonts. Key Features Smart Asset Detection: Automatically detects which themes and plugins are from wordpress.org and only serves those via CDN. Custom themes and plugins are served locally. No configuration needed! Failure Memory System: If a CDN resource fails to load, the plugin remembers and automatically serves it locally for 24 hours. No more repeated failures! Automatic URL Rewriting: Automatically rewrites URLs of enqueued styles, scripts, and core files for themes, plugins, and WordPress itself to use the StaticDelivr CDN. Image Optimization: Automatically optimizes images with compression and modern format conversion (WebP, AVIF). Turn 2MB images into 20KB without quality loss! Google Fonts Privacy Proxy: Serve Google Fonts without tracking (GDPR compliant). A drop-in replacement that strips all user-identifying data and tracking cookies. Automatic Fallback: If a CDN asset fails to load, the plugin automatically falls back to your origin server, ensuring your site never breaks. Localhost Detection: Automatically detects development environments and serves images locally when CDN cannot reach them. Child Theme Support: Intelligently handles child themes by checking parent theme availability on wordpress.org. Separate Controls: Enable or disable assets (CSS/JS), image optimization, and Google Fonts proxy independently. Quality & Format Settings: Customize image compression quality and output format. Verification Dashboard: See exactly which assets are served via CDN vs locally in the admin panel. Failure Statistics: View which resources have failed and are being served locally, with option to clear cache. Compatibility: Works seamlessly with all WordPress themes and plugins — both from wordpress.org and custom/premium sources. Improved Performance: Delivers assets from the StaticDelivr CDN for lightning-fast loading and enhanced user experience. Multi-CDN Support: Leverages multiple CDNs to ensure optimal availability and performance. Free and Open Source: Supports the open-source community by offering free access to a high-performance CDN. Use of Third-Party Service This plugin relies on the StaticDelivr CDN to deliver static assets, including WordPress themes, plugins, core files, optimized images, and Google Fonts. The CDN uses the public WordPress SVN repository to fetch theme/plugin files and serves them through a globally distributed network for faster performance and reduced bandwidth costs. Service Terms of Use: StaticDelivr Terms Privacy Policy: StaticDelivr Privacy Policy How It Works StaticDelivr CDN rewrites your WordPress asset URLs to deliver them through its high-performance network: Smart Asset Detection The plugin automatically verifies which themes and plugins exist on wordpress.org: WordPress.org Assets: Served via StaticDelivr CDN for maximum performance Custom/Premium Assets: Automatically detected and served from your server Child Themes: Parent theme is checked. If the parent is on wordpress.org, assets load via CDN This means the plugin “just works” with any combination of wordpress.org and custom themes/plugins! Failure Memory System (New in 1.7.0!) The plugin learns from CDN failures and automatically adapts: First failure: Fallback fires, failure is recorded Second failure: Resource is blocked from CDN for 24 hours Auto-recovery: After 24 hours, resources are retried automatically Manual reset: Clear the failure cache anytime from settings This ensures that problematic resources (Cloudflare-protected images, auth-gated content, etc.) are handled gracefully without repeated failures. Assets (CSS & JavaScript) Original URL: `https://example.com/wp-content/themes/theme-name/version/style.css` Rewritten CDN URL: `https://cdn.staticdelivr.com/wp/themes/theme-name/version/style.css` This process applies to themes, plugins, and core files: Themes: Original: `https://example.com/wp-content/themes/twentytwentythree/1.0/style.css` CDN: `https://cdn.staticdelivr.com/wp/themes/twentytwentythree/1.0/style.css` Plugins: Original: `https://example.com/wp-content/plugins/woocommerce/assets/js/frontend/woocommerce.min.js` CDN: `https://cdn.staticdelivr.com/wp/plugins/woocommerce/tags/9.3.3/assets/js/frontend/woocommerce.min.js` Core Files: Original: `https://example.com/wp-includes/js/jquery/jquery.min.js` CDN: `https://cdn.staticdelivr.com/wp/core/tags/6.9/wp-includes/js/jquery/jquery.min.js` Images Original: `https://example.com/wp-content/uploads/2024/01/photo.jpg` (2MB) Optimized CDN: `https://cdn.staticdelivr.com/img/images?url=https://example.com/wp-content/uploads/2024/01/photo.jpg&q=80&format=webp` (~20KB) Google Fonts Original CSS: `https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600&display=swap` Privacy Proxy: `https://cdn.staticdelivr.com/gfonts/css2?family=Inter:wght@400;500;600&display=swap` Original Font Files: `https://fonts.gstatic.com/s/inter/v20/example.woff2` Privacy Proxy: `https://cdn.staticdelivr.com/gstatic-fonts/s/inter/v20/example.woff2` This ensures faster delivery through StaticDelivr’s globally distributed network while protecting user privacy. Why Use StaticDelivr? Zero Configuration: Smart detection means it works out of the box with any theme/plugin combination. Self-Healing: Failure memory system automatically adapts to problematic resources. Global Distribution: StaticDelivr serves your assets from a globally distributed network, reducing latency and improving load times. Massive Bandwidth Savings: Offload heavy image delivery to StaticDelivr. Optimized images can be 10-100x smaller! Privacy-First Google Fonts: Serve Google Fonts without tracking cookies — GDPR compliant without additional cookie banners. Works with Custom Themes: Unlike other CDN plugins, StaticDelivr automatically detects custom themes/plugins and serves them locally. Browser Caching Benefits: As an open-source CDN used by many sites, assets served by StaticDelivr are likely already cached in users’ browsers. This enables faster load times when visiting multiple sites using StaticDelivr. Significant Bandwidth Savings: Reduces your site’s bandwidth usage and number of requests significantly by offloading asset delivery to StaticDelivr. Optimized Performance: Ensures assets are delivered quickly, no matter where your users are located. Comprehensive WordPress Support: Includes support for delivering core WordPress files (e.g., those in the `wp-includes` directory) to enhance site speed and reliability.

DietPress is a free WordPress speed optimization plugin with a built-in page cache. Page caching, browser caching, GZIP and Brotli compression, deferred JavaScript, critical CSS, image loading attributes, preloading, locally hosted Google Fonts and selective asset loading, all in one plugin and all free. And it goes further than a caching plugin: it also puts WordPress itself on a diet, switching off the features your site never uses. It pairs that with a clean, risk-based interface. Everything is configurable, the optimizations are already on by default, and nothing is hidden behind a paid tier. Activate it and your site is faster, or open the settings and tune every detail. 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. WHY CHOOSE DIETPRESS Page caching, for free. Serve anonymous visitors a copy stored on disk instead of building the page again. The feature people buy WP Rocket or a NitroPack subscription for, with no licence and no monthly fee. No drop-in, no changes to wp-config.php. Unlike WP Super Cache or W3 Total Cache, DietPress installs no advanced-cache.php and never edits wp-config.php. Switching it off leaves your site exactly as it was, with nothing orphaned behind. It tells you why. Most cache plugins leave you guessing when nothing is cached. DietPress reports its own status, tests itself against your home page, and names the exact reason a page was skipped. WooCommerce-safe by design. Carts, checkout, my account and any visitor carrying a cart cookie always get the live site, so nobody ever sees somebody else’s basket. Diet as well as speed. Where Perfmatters focuses on disabling scripts, DietPress covers that ground and adds page caching, critical CSS, local Google Fonts and a dashboard, admin and email cleanup, in one plugin. Light on your server. No account, no external service, no telemetry, no upsell nags. Everything runs on your own hosting. WHAT THE PAGE CACHE DOES TO YOUR RESPONSE TIME Measured on a WordPress 7.0 install with GeneratePress, WooCommerce and a 76 product catalogue, PHP 8.5, taking the median of 15 requests per URL. Your own hosting will give different figures, but the shape of the result will not change. Server response time, the same pages with the page cache off and on: Home page – 52.7 ms without, 15.1 ms with, 71% faster WooCommerce shop – 45.4 ms without, 14.8 ms with, 67% faster A 110 KB article – 43.0 ms without, 15.1 ms with, 65% faster A 98 KB page – 41.0 ms without, 14.9 ms with, 64% faster A product category – 41.3 ms without, 15.1 ms with, 63% faster The interesting part is not the percentage, it is that the cached figure barely moves. Serving a stored file costs the same whether the page was cheap or expensive to build, so the saving grows with the size of your site rather than with the power of your server. The heaviest page in the test is the one that gained most. It also changes how much traffic your hosting can take at once. In the same test the server went from serving about 40 visits a second to more than 210, five times as many, on exactly the same plan. That is what keeps a small site standing up when one of your posts does well. TWO THINGS IN ONE PLUGIN 1. Performance optimizations (on by default) Automatic Critical CSS inlined in the head (optional experimental deferral of non-critical CSS) JavaScript defer parsing with smart dependency handling Image loading attributes safety net: lazy loading, decoding=async and fetchpriority for images that bypass core Automatic image dimensions for better CLS scores (including picture elements) Resource hints: preconnect and DNS prefetch for common third-party origins Theme stylesheet, critical fonts and logo preloading for a faster LCP Google Fonts display=swap Google Fonts local hosting: serve the fonts your theme uses from your own server, GDPR-friendly with a silent fallback to the Google CDN (opt-in) Selective third-party loading: WooCommerce, Contact Form 7, block library, Slider Revolution, TablePress, Smash Balloon, Formidable Forms and Everest Forms assets only load where they are used (opt-in) RSS feed optimization (cache headers and item limit) Server rules in .htaccess: browser caching with a configurable lifetime for media, for styles and scripts and for fonts, GZIP and Brotli compression, immutable cache headers, CORS for fonts and keep-alive (master switch plus per-feature toggles) Database maintenance: daily expired-transient cleanup and safe query optimizations Page cache: store each page on disk and serve it to anonymous visitors without building it again, with automatic purging, gzip precompression and a status panel that says whether it is working (opt-in, in its own tab) 2. Put WordPress on a diet (risk-based, opt-in) Light (safe for any site): emojis, RSD/WLW tags, shortlinks, self-pingbacks, comment pagination, and more Moderate (evaluate first): oEmbed, jQuery Migrate, Dashicons on the frontend, Global Styles and Duotone, remote block patterns, avatars and Gravatar, comment threading, and more Strict (site-specific): granular RSS feed control, Heartbeat API mode, post revisions and autosave, disable comments, XML sitemap, native lazy loading/fetchpriority, content types, selective loading for WooCommerce, Contact Form 7, block assets, Slider Revolution, TablePress, Smash Balloon, Formidable Forms and Everest Forms, and more 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 Emails: silence the automatic emails WordPress sends on its own, grouped by area: auto-update results for core, plugins and themes (plus the new-version notice), comment moderation and new-comment notices, and new user, password and email-change notices, plus toggles for the admin email verification prompt and post-by-email. Every option is off by default, and critical notices such as a failed core update are always kept SCALE, PROFILES AND ANALYZER Savings indicator: HTTP requests removed, CSS/JS saved and active optimizations at a glance Quick profiles: Personal Blog, WooCommerce Store, Landing Page and Maximum Cleanup Site analyzer: personalized recommendations based on your active plugins and content, page cache included Import and export your whole configuration as a JSON file COMPATIBILITY AND EXTENSIBILITY The plugin includes filters for developers: dietpress_critical_css – Customize the inline critical CSS dietpress_critical_css_handles – Define which CSS handles are critical dietpress_skip_defer_script_handles – Opt scripts out of the JavaScript defer dietpress_skip_defer_style_handles – Opt stylesheets out of the CSS deferral dietpress_preconnect_hints – Customize preconnect origins dietpress_dns_prefetch_domains – Customize DNS prefetch domains dietpress_critical_fonts – Define critical fonts to preload dietpress_exclude_local_fonts – Exclude Google Fonts stylesheets from local hosting dietpress_selective_{module}_has_content – Mark a page as showing the content of a selective loading module, so its assets are kept. The module is wc, cf7, formidable, everest_forms or revslider dietpress_selective_{module}_styles / dietpress_selective_{module}_scripts – Adjust the handles removed by each module dietpress_selective_page_hides_content – Mark a page as rendering content the content scan cannot reach, so no module removes anything (this is what handles Elementor) dietpress_selective_is_wc_page – Override the WooCommerce page detection of selective loading dietpress_selective_wc_keep_cart_fragments – Keep the cart fragments script when your theme has a hand-coded mini-cart dietpress_selective_cf7_has_form – Mark pages that load a Contact Form 7 form dynamically dietpress_selective_blocks_dequeue – Override the block library dequeue decision dietpress_selective_everest_forms_dequeue_dashicons – Keep Dashicons when another plugin enqueues it directly dietpress_native_sitemap_in_use – Tell DietPress your plugin builds on the native WordPress sitemap, so the option that removes it becomes unavailable dietpress_cache_bypass – Keep the current page out of the page cache dietpress_cache_bypass_cookies – Adjust the cookie name prefixes that make a visitor uncacheable dietpress_cache_ignored_params – Adjust the query parameters that do not change the page dietpress_cache_exclude_urls – Adjust the excluded URL patterns dietpress_cache_post_urls – Adjust the URLs purged along with a post Compatible with: Well-coded themes and page builders (Divi, Elementor, Beaver Builder, Bricks Gutenberg) Cache plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, etc.). The one exception is the optional page cache module, which will not run beside another page cache and says so; everything else in DietPress works alongside them as it always has Security plugins (DietPress focuses on performance and deliberately leaves security to them; we recommend our free Vigilant) CDNs (Cloudflare, StackPath, KeyCDN, etc.) thanks to CORS and Vary headers WordPress Multisite (except the optional page cache module, which does not support it yet) HOW TO VERIFY THE OPTIMIZATIONS Cache rules: check your .htaccess for a block marked # BEGIN DietPress with immutable Cache-Control headers Logo preload: view page source and look for pointing to your logo Critical CSS: view source and look for in the head Compression: test at giftofspeed.com/gzip-test Always measure with tools like Google PageSpeed, GTMetrix or WebPageTest, and run each test at least twice to account for caching.
