A built-in performance test\nmeasures what it changes on your own pages, with and without SlimPress, without changing a setting.<\/p>\n\n<p>What makes it different:<\/p>\n\n<ul>\n<li><strong>Every toggle is free.<\/strong> No pro tier, no upsells, no nag banners, no telemetry.<\/li>\n<li><strong>\"What might break\" on every switch<\/strong>, plus a warning when an active plugin needs the thing\nyou are about to switch off.<\/li>\n<li><strong>An honest impact badge<\/strong> on every toggle, including \"None - cleanup only\".<\/li>\n<li><strong>A performance test that tells the truth.<\/strong> It loads your pages with SlimPress's features and\nwithout them, in the same run, and says \"within noise\" when the difference is too small to\ntrust - and shows what each plugin, theme and core adds to the page, with the files SlimPress\ncan remove marked.<\/li>\n<\/ul>\n\n<p>What SlimPress deliberately does not do: page caching, minification, \"remove unused CSS\",\ndelay-JS, per-page script managers, CDN rewrites. If a feature is not \"turn off something core\nWordPress does\", it does not go in.<\/p>\n\n<p>Nothing is switched off until you switch it off. Every switch is a runtime filter, so\ndeactivating SlimPress restores WordPress completely on the next request. SlimPress never writes to\ncore tables or core options.<\/p>\n\n<h4>108 switches in 13 groups<\/h4>\n\n<ul>\n<li><strong>Front-end<\/strong> - emoji scripts, generator tag, RSD, shortlink and REST links in the page head,\nglobal styles, core block CSS, Dashicons and jQuery Migrate for visitors.<\/li>\n<li><strong>APIs &amp; connections<\/strong> - XML-RPC, the REST API for logged-out visitors (with an allowlist),\nHeartbeat per location, WP-Cron on page load, oEmbed, auto-embeds, application passwords, the\nAbilities API.<\/li>\n<li><strong>Comments<\/strong> - comments site-wide or per post type, pingbacks, avatars and Gravatar.<\/li>\n<li><strong>Content &amp; URLs<\/strong> - feeds, author, date and attachment pages, search.<\/li>\n<li><strong>Revisions &amp; autosave<\/strong> - revision limits, autosave interval, trash retention, plus a\none-off \"delete old revisions\" button that asks first.<\/li>\n<li><strong>Media<\/strong> - the extra 1536px and 2048px image copies, image sizes you choose, and Openverse\nin the media inserter.<\/li>\n<li><strong>Block editor<\/strong> - welcome guide, block directory, command palette, the classic editor for\nchosen post types.<\/li>\n<li><strong>Dashboard &amp; admin<\/strong> - dashboard widgets, admin bar items, footer text, the Customizer on\nblock themes.<\/li>\n<li><strong>Updates<\/strong> - automatic updates for core, plugins, themes and translations.<\/li>\n<li><strong>Emails<\/strong> - the admin emails WordPress sends about updates, new users and password changes.<\/li>\n<li><strong>Security<\/strong> - file editing, installing from the dashboard, the front-end password meter.<\/li>\n<li><strong>Site Health &amp; privacy<\/strong> - Site Health checks and the privacy tools menus.<\/li>\n<li><strong>WooCommerce<\/strong> (only shown while WooCommerce is active) - shop assets and order attribution\nscripts on non-shop pages, Analytics, the Marketing hub, remote and marketplace suggestions,\nusage tracking, background thumbnail regeneration, and how long Action Scheduler and log files\nare kept.<\/li>\n<\/ul>\n\n<p>Each group has an on\/off switch of its own, so you can pause a whole group while you look for a\nproblem, and put it back exactly as it was.<\/p>\n\n<h4>Presets<\/h4>\n\n<p>The Overview tab offers site-wide presets (Safe defaults, Blog, Brochure site, WooCommerce store,\nHeadless). A preset only ever switches things on: it shows you what it would change first,\nskips anything an active plugin relies on, and leaves everything else as it is.<\/p>\n\n<h4>Built to cost nothing<\/h4>\n\n<p>A feature that is off loads no code and adds no hooks. SlimPress adds no CSS, JavaScript or\nmarkup to your public pages, ever. With every feature off, SlimPress adds about 105 KB of memory\nand no database queries to a front-end request, and the time it adds was too small to measure\n(WordPress 7.1, PHP 8.4, median of 40 paired runs).<\/p>\n\n<h3>External services<\/h3>\n\n<p>The performance test tab has an optional \"Run Google PageSpeed test\" button. Only when you click it,\nSlimPress sends your site's homepage URL to Google's PageSpeed Insights API\n(<code>https:\/\/www.googleapis.com\/pagespeedonline\/v5\/runPagespeed<\/code>) to fetch Core Web Vitals for that\npage. No other data is sent, no API key is used, and nothing is sent automatically.<\/p>\n\n<p>This service is provided by Google: <a href=\"https:\/\/developers.google.com\/terms\">Terms of Service<\/a>,\n<a href=\"https:\/\/policies.google.com\/privacy\">Privacy Policy<\/a>.<\/p>\n\n<!--section=installation-->\n<ol>\n<li>Upload the plugin to <code>\/wp-content\/plugins\/slimpress\/<\/code>, or install it from the Plugins screen.<\/li>\n<li>Activate it.

SlimPress applies everything through runtime\nfilters and actions, so there is nothing to undo. The one exception is the \"Delete old\nrevisions\" button: revisions it deleted stay deleted, which is why it asks first.<\/p><\/dd>\n<dt id=\"which%20toggles%20are%20risky%3F\"><h3>Which toggles are risky?<\/h3><\/dt>\n<dd><p>Every toggle that can visibly break something is marked <strong>Careful<\/strong> and says what might stop\nworking. The ones most likely to catch you out:<\/p>\n\n<ul>\n<li><strong>Disable the REST API for logged-out visitors<\/strong> - contact forms, booking plugins and\nWooCommerce blocks often use it. Add their namespaces to the allowlist.<\/li>\n<li><strong>Disable WP-Cron on page load<\/strong> - scheduled posts, backups and automatic updates stop until\na real server cron job runs <code>wp-cron.php<\/code>. Set that up first.<\/li>\n<li><strong>Disable XML-RPC<\/strong> - the WordPress mobile app, Jetpack and pingbacks use it.<\/li>\n<li><strong>Disable comments site-wide<\/strong> - WooCommerce product reviews are comments too.<\/li>\n<li><strong>Disable global styles<\/strong> - block themes rely on it for spacing, colours and typography.<\/li>\n<li><strong>Disable installing and updating from the dashboard<\/strong> - also stops security updates. Only\nfor sites that are updated some other way.<\/li>\n<li><strong>Disable recovery mode emails<\/strong> - that email is how you get back in after a fatal error.<\/li>\n<\/ul>\n\n<p>SlimPress also warns you when an active plugin is known to need something you are about to switch\noff.<\/p><\/dd>\n<dt id=\"why%20doesn%27t%20slimpress%20remove%20%3Fver%3D%20query%20strings%3F\"><h3>Why doesn't SlimPress remove ?ver= query strings?<\/h3><\/dt>\n<dd><p>The version string is what makes browsers fetch a fresh file after an update. Removing it gains\nnothing measurable and can serve visitors stale CSS and JavaScript. SlimPress also has no switch\nfor turning off lazy loading, auto <code>sizes<\/code> on lazy images or big-image scaling, because each of\nthose makes sites slower. The Media tab explains big-image scaling on an info card instead.<\/p><\/dd>\n<dt id=\"does%20slimpress%20need%20woocommerce%3F\"><h3>Does SlimPress need WooCommerce?<\/h3><\/dt>\n<dd><p>No. It works on any site. On a WooCommerce store it warns you about switches the shop relies on,\nand there is a WooCommerce store preset that leaves the shop alone. A WooCommerce tab with its own\nswitches (admin nags, tracking, background jobs and more) appears automatically while WooCommerce\nis active, and disappears - without losing your choices - if you deactivate it.<\/p><\/dd>\n<dt id=\"will%20it%20conflict%20with%20my%20caching%20plugin%3F\"><h3>Will it conflict with my caching plugin?<\/h3><\/dt>\n<dd><p>SlimPress does not cache, minify or combine anything, so it does not overlap with a caching\nplugin. The performance test asks for uncached pages, and if a page cache answers anyway it says\nso rather than showing you the cache's numbers.<\/p><\/dd>\n<dt id=\"does%20slimpress%20contact%20any%20external%20service%3F\"><h3>Does SlimPress contact any external service?<\/h3><\/dt>\n<dd><p>Only if you click the optional PageSpeed button on the performance test tab. See \"External\nservices\" below.<\/p><\/dd>\n<dt id=\"can%20i%20move%20my%20settings%20to%20another%20site%3F\"><h3>Can I move my settings to another site?<\/h3><\/dt>\n<dd><p>Yes. The Tools tab exports your settings as a JSON file and imports them on another site. It\nalso resets every switch to off.<\/p><\/dd>\n\n<\/dl>\n\n<!--section=changelog-->\n<h4>Unreleased<\/h4>\n\n<ul>\n<li>Removed the \"Disable all update checks\" option at the request of the wordpress.org plugin\nreview team: it interfered with the WordPress update system.
