v1.0.0WordPress loads emoji scripts, answers XML-RPC, polls Heartbeat and keeps every revision whether your site uses them or not. This switches off the ones it does not, one plain-language switch at a time.
Nothing is switched off until you switch it off. Every switch is a runtime filter, so nothing is written to core tables and there is nothing to undo.
Front-end, APIs and connections, comments, content and URLs, revisions, media, block editor, dashboard, updates, emails, security, Site Health, and WooCommerce when it is active. Each group has its own switch, so you can pause a whole group while you look into a problem.
Every switch says in plain language what it changes and what could stop working. The risky ones are marked Careful, and you are warned when an active plugin relies on the thing you are about to switch off.
Each switch is rated for what it actually saves, including "None, cleanup only" where that is the truth.
It loads your own pages with and without SlimPress in the same run, and says "within noise" when the difference is too small to trust. It also shows what each plugin, the theme and core add to the page.
Safe defaults, Blog, Brochure site, WooCommerce store and Headless. A preset only ever switches things off, shows what it would change first, and skips anything an active plugin relies on.
Deactivate it and WordPress is back to stock on the very next request. The one exception is the delete old revisions button, which asks first.
A switch that is off loads no code and adds no hooks. With every feature off it adds about 105 KB of memory and no database queries to a front-end request.
Settings move between sites as a JSON file from the Tools tab, and one reset puts every switch back to off.
If a feature is not "turn off something core WordPress does", it does not go in. That keeps it out of the way of your caching plugin.
No page caching, so it does not overlap your caching plugin.
Nothing is minified, combined or rewritten.
No "remove unused CSS" and no delay-JS.
No per-page script manager and no CDN rewrites.
Left alone. Removing them saves nothing measurable and can serve visitors stale CSS and JavaScript.
Left alone, along with auto sizes and big-image scaling. Removing each of them makes sites slower.
Straight from the WordPress.org listing, so what you see here is what the plugin actually renders.
It works on any site. On a WooCommerce store it warns you about the switches the shop relies on, and adds a WooCommerce tab while WooCommerce is active.
6.8 or higher, tested up to 7.1.2.
7.4 or higher.
Optional. Its tab appears while WooCommerce is active, and disappears without losing your choices if you deactivate it.
None, unless you click the optional PageSpeed button, which sends your homepage URL to Google PageSpeed Insights.
GPLv2 or later.
