How it works
Add the snippet
Paste one script tag into your site, with the two short lines that stop a flash of the old page. The dashboard shows when it's installed and when the last event arrived.
Build a test
Open the visual editor, click what you want to change (text, colours, images, links, layout) and preview it. Pick a goal: a click or a page view.
Read the result
See visitors and conversions for each version, with a plain-language verdict: not enough data yet, no clear difference, leading, or likely better. Results are built to hold up when you check early.
What you get
Results you can trust
A verdict that stays valid however often you check. No calling a winner on a lucky first day.
Visual editor
Click to change text, colours, images, links and layout. Preview before you start.
Test more than two versions
Run an A/B/n test with up to 5 versions of a page at once on paid plans (3 on Free).
Goals and guardrails
One main goal plus extra metrics, with a warning when a variant hurts one.
Works with your stack
Works with single-page apps. Google Analytics 4 hand-off and visitor targeting by device, source and new vs returning on paid plans.
Stays in the loop
Emails when the snippet stops reporting, and on paid plans when a test reaches significance.

FAQs
Will the snippet slow my site down?
It's a small script, about 6 KB compressed, with no framework inside. It only changes pages that have a running test. The install code also hides the page while the snippet loads, for at most 1 second.
Will visitors see a flash of the old page?
Not with the full install code: its two hide lines keep the page hidden until the change is applied, and show it after 1 second at the latest.
Does it use cookies?
No. It uses browser storage, listed on the Snippet privacy page; custom JavaScript you add is your own code. If you need consent, load it after your banner.
What sites does it work on?
Any website where you can add a script tag to your pages, whatever it's built with. Tests run in your visitors' browsers, so it can't test server-side code, emails or mobile apps. The dashboard is in English.
Do I need to write code?
No. Build each test in the visual editor by clicking on your page: change text, colours, images, links and layout, and preview it before you start. On Growth you can also run your own JavaScript in a variant.
Does it work with single-page apps?
Yes, for sites that change pages with the browser's History API, such as React Router, Next.js and Vue Router. A change is applied when the page changes; content your app re-renders afterwards isn't re-patched.
Does it work with Google Analytics?
Yes. On the Starter plan and above, turn on the Google Analytics 4 hand-off in a project's settings and each visitor's version is sent to your GA4 as an event. It needs the Google tag or Google Tag Manager on your site.
What counts as a tested session?
A tested session is one visit in which someone is shown the original or a variant of a running test, counted once for each test. A visitor who comes back later, or opens another tab, counts again. Pages without a running test don't count.
What happens if I go over my plan?
The dashboard warns you at 80% of your plan's sessions. Tests keep running up to 125%, then pause until next month or an upgrade. We email you when you reach your plan's sessions, and again if tests pause. While tests are paused, visitors see your original pages.
Can I cancel?
Yes. Starter and Growth are month to month and renew automatically, with no annual contract. Cancel any time with Manage billing on the Billing page of your dashboard; your plan runs to the end of the period you've paid for, then moves to Free.
Can I get a refund?
Yes. Ask within 14 days of a charge for Starter or Growth and we refund it in full, for any reason. See the Refund policy.
