Features and specs

What each product offers, as listed by its team.

SlimPress.dev 7 features
WP-Optimize 5 features
  • Switches in 13 groups
    Front-end, APIs, comments, content, revisions, media, block editor, dashboard, updates, emails, security, Site Health and WooCommerce, each switch in plain language.
  • "What might break" on every switch
    an impact badge and a warning if an active plugin relies on the feature.
  • Undo for every change
    the last 10 versions of its settings are kept, and any save, preset, import or reset can be restored.
  • Built-in performance test
    compares your pages with and without SlimPress, and says "within noise" when the difference is too small to trust.
  • Assets tab
    load a plugin's CSS and JavaScript only on the pages that use it, with a plugin scan showing the size each one adds.
  • Presets
    Safe defaults, Blog, Brochure site, WooCommerce store and Headless.
  • Nothing until you switch it
    no code or hooks load for features that are off, there's no pro tier or telemetry, and deactivating it restores WordPress's defaults.
  • Database Optimization
    WP-Optimize provides robust tools for cleaning up and optimizing the WordPress database by removing unnecessary data such as post revisions, spam comments, and expired transients, which can improve overall site performance.
  • Cache Management
    The plugin includes caching features that help to speed up the website by storing static versions of dynamic pages, thereby reducing server load and improving load times for users.
  • Image Compression
    WP-Optimize offers image compression capabilities that can automatically compress images upon upload, reducing file sizes without noticeable loss of quality, which helps in improving site speed.
  • Easy to Use Interface
    It provides a user-friendly interface that allows even non-technical users to easily navigate, configure settings, and perform optimization tasks without needing deep technical knowledge.
  • Scheduled Cleanup
    Users can set up automated optimization schedules for regular clean-ups, reducing the need for manual intervention and ensuring that the site maintains optimal performance over time.

Possible disadvantages

  • Potential Data Loss
    If not configured correctly, the database optimization features can result in accidental deletion of important data, such as post revisions or draft posts.
  • Limited Free Features
    The free version of WP-Optimize offers only basic functionalities, and more advanced features like multisite support and certain premium optimizations are locked behind a paywall.
  • Compatibility Issues
    There could be compatibility issues with some themes and plugins, potentially leading to site errors or conflicts that could require technical troubleshooting.
  • Performance Overhead
    Although designed to optimize performance, running too many optimization tasks or settings can sometimes lead to increased server load, ironically slowing down the website.
  • Limited Support
    Users of the free version may find support limited, as dedicated customer support is typically reserved for premium users, making it challenging to resolve issues promptly.

Questions & Answers

As answered by people managing SlimPress.dev and WP-Optimize.

What makes your product unique?

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.

How would you describe the primary audience of your product?

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).

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

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.

Why should a person choose your product over its competitors?

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.
