WordPress speed plugin · free for one site

One switch.
Faster WordPress.
Nothing to break.

Speed plugins break sites because they ask forty questions you can't answer. ZeroConfig asks none. Turn it on and the heavy work runs on our servers instead of your hosting. Then a real browser checks your pages and switches off anything that doesn't suit your theme.

Sound familiar?

The plugin that promised speed is the plugin that broke your site.

Most people running WP Rocket or LiteSpeed Cache are not developers, and the checkboxes don't come with a warning label.

F-01

"Minify CSS" and the layout shifts

One box, and the header jumps to the bottom of the page. Unticking it doesn't always bring it back.

F-02

"Delay JavaScript" and the slider dies

The hero slider freezes on the first slide. Forms stop submitting.

F-03

"Optimize images" and the server struggles

Converting thousands of photos with PHP pushes a cheap host to 100 % CPU.

ZeroConfig removes the checkboxes. The engine decides. A real browser checks.

If a feature doesn't suit your theme, that one feature is switched off.

How it works

Your server serves cached pages. Our servers do the heavy work.

1

Turn it on

Install and press Turn on. The plugin confirms the site is yours, reads which theme and plugins you use and loads matching safety rules. No account, no form. The plugin tells you exactly what it sends before you press the button.

2

We rewrite, our servers optimise

Pages are cached on your server and served before WordPress even loads. Image, CSS and JS addresses point to our servers, which convert images to WebP or AVIF in the sizes your pages ask for and minify CSS and JS. Your hosting does no image work.

3

A real browser checks the result

A few minutes later, headless Chrome renders your pages with and without each feature. A new JavaScript error, a visible layout change or extra layout shift switches that one feature off.

Features

Everything a faster site needs.

The same speed techniques the big plugins use, minus the settings that break sites.

Free

Page cache

Pages are cached on your server and served before WordPress even loads. Cart, checkout and account pages are never cached.

Free

WebP & AVIF images

Converted on our servers in the sizes your pages ask for. Your hosting does no image work and originals stay untouched.

Free

Minify & safe defer

CSS and JavaScript minified at the edge, with JavaScript deferral that skips what would break.

Pro

Automatic critical CSS

Generated for phone and desktop, then checked so the page doesn't jump when the full stylesheet arrives.

Pro

Third-party script delay

Tag Manager, Pixel and chat widgets wait until the visitor interacts, so they stop competing with your content.

Pro

Score Guard

A weekly PageSpeed check with an e-mail when your score drops, so a theme update doesn't quietly undo your work.

Safety Check

A speed plugin that checks its own work.

Other plugins hope their defaults suit your theme. ZeroConfig checks. A few minutes after you turn it on, and again after theme or plugin updates, our servers load your home page, a post, a page and a product in headless Chrome on a phone and a desktop, once with ZeroConfig off and once per feature:

  • T-1New JavaScript errors → that feature is switched off
  • T-2More than 8 % of the screen changed → that feature is switched off
  • T-3Layout shift grew → that feature is switched off
  • T-4Images fail to load from our servers → your original images are used

Only the feature that caused the problem is turned off; everything else stays on, and the plugin tells you why. If something still looks wrong, the Something looks off? button runs a stricter check right away.

Paid plans open after our beta: leave your e-mail below and we'll tell you first. Plans are billed yearly through Polar.sh, our merchant of record, and renew automatically; cancel any time from your customer portal. Images are counted per source image: every size and format of one photo counts once. When a site reaches its monthly limit nothing breaks; new images come from your own server until the month resets.

FAQ

Questions people ask before flipping the switch.

Will it break my site?

Anything can break a site, which is why the engine checks itself. Features switch on as soon as you press Turn on. A few minutes later a real browser loads your home page, a post, a page and a product with each feature on and off and compares them. A feature that changes how your site looks or causes new JavaScript errors is switched off on its own, and the plugin shows you why. If you ever see something odd, press "Something looks off?" and a stricter check runs right away.

What do you send to your servers?

Nothing until you press Turn on. After that: your site address and name, WordPress and PHP versions, the names of your active theme and plugins, the web server type and the plugin's own settings. Our servers fetch your public images, CSS and JavaScript files to optimise them, and load a few public pages for the Safety Check. Visitor data, user accounts, orders, form entries and passwords are never sent. Your admin e-mail is only shared if you tick the box. Privacy policy

Where do my images live?

Originals stay on your server and are never changed. We keep optimised copies on our servers so the next visitor gets them straight away. Turn the engine off and every address points back to your own server.

Does it work with WooCommerce, Elementor, Divi, Bricks…?

Yes. Cart, checkout and account pages are never cached. Builders, sliders and payment scripts are on our known-safe list, which we update on our side without a plugin update. Divi and a few premium themes run with critical CSS off by default because they ship their own.

Does it work on managed hosting like WP Engine or Kinsta?

Image and file optimisation work everywhere. Managed hosts run their own page cache in front of WordPress; automatic detection of those caches is on our list for an upcoming release. Until then, e-mail us before installing on a managed host and we'll tell you what to expect.

What happens if ZeroConfig is down?

Your pages keep loading from the page cache on your own server, and images switch back to your originals after a short check. Your site gets slower for a while; it doesn't go down because of us.

Do I need to remove WP Rocket / LiteSpeed first?

Yes. Running two optimisers is slower than running one and they fight over the same files. The plugin warns you if it sees one. Deactivate it, then turn on ZeroConfig.

What is your refund policy?

30 days from your first payment: e-mail us and we refund it in full, no questions asked. A yearly renewal can be refunded within 14 days if you tell us you didn't want it. Refund policy

Why yearly only?

Speed is not a one-month project: themes update, plugins update, Google moves the goalposts. Yearly keeps the price low ($3.25 a month for Pro) and lets us run Score Guard every week instead of chasing card renewals.

Who handles payment?

Polar.sh is our merchant of record. You pay Polar, they handle the checkout, receipts and sales tax or VAT, and you manage or cancel your subscription from their customer portal.

What is the badge on the Free plan?

Optional. Tick one box in the plugin and a small "⚡ Powered by ZeroConfig" tag appears in the bottom corner of your site. It is added after the page loads, so it costs nothing on Core Web Vitals, and it never shows on cart, checkout or account pages. In return your free limits double to 1,000 images and 10 GB a month. Untick it any time; paid plans never show a badge.

Is there a lifetime deal?

No. A lifetime deal means we'd eventually be paying for your traffic out of pocket, and the product would die. Agencies get the best per-site price instead.

Install.
Turn on.
Done.

Free for one site, no card. Setup takes about a minute; the Safety Check finishes in the background a few minutes later.
