As answered by people managing Cachify and SlimPress.dev.
SlimPress.dev's answer:
Every switch says what it might break, and SlimPress warns you if an active plugin relies on the feature you're about to turn off. Any change can be undone from the last 10 saved versions of its settings. A built-in performance test loads your own pages with and without SlimPress and says "within noise" when the difference is too small to trust, instead of overselling. Every toggle is free: no pro tier, no upsells, no telemetry.
SlimPress.dev's answer:
WordPress site owners, freelancers and agencies who want a leaner site and want to understand each change before making it. It suits blogs, brochure sites and WooCommerce stores, and includes presets for each (Safe defaults, Blog, Brochure site, WooCommerce store and Headless).
SlimPress.dev's answer:
I built SlimPress because on shop sites I kept switching off the same parts of WordPress core by hand, and I wanted each switch to say what it might break. It grew into a plugin with grouped switches, an undo history and a performance test that reports the real difference on your own pages. I publish it free, with no pro version, as part of PluginLab.dev.
SlimPress.dev's answer:
PHP and JavaScript for WordPress, written as plain, readable source with no build step. It requires WordPress 6.8 or higher and PHP 7.4 or higher, and applies its changes through WordPress filters and actions at runtime. An optional PageSpeed button calls Google's PageSpeed Insights API only when you click it. It also integrates with WooCommerce when WooCommerce is active.
SlimPress.dev's answer:
SlimPress is free and open source, so it has no paying customers. It is installed from WordPress.org by site owners, agencies and WooCommerce shops, and it has no telemetry, so I don't track or name them.
SlimPress.dev's answer:
It focuses on one job: turning off parts of WordPress core your site doesn't use, and it is open about what each change costs. Nothing is switched off until you choose to, and deactivating SlimPress puts WordPress back exactly as it was, because every switch is a runtime filter. It adds no CSS, JavaScript or markup to your pages, and it deliberately skips caching, minification and CDN rewrites, so it works alongside the performance tools you already use.
