Split tests for any website, run by your AI agent.
AB Split Test Cloud runs the AB Split Test engine on sites that are not WordPress. Paste one script tag into the <head> of a static site, Webflow, Framer, Shopify, Next.js or Astro. Then ask your agent for a test: it builds it through the Cloud MCP tools and it goes live at once. 100,000 MTUs free, no card. Start testing
Why use AB Split Test Cloud?
One script tag
Add one tag to the <head> of every page. It hides the page for at most 1.5 seconds while it loads, so visitors never see a flash of the original.
Your agent runs the tests
Claude, ChatGPT, Cursor or any MCP client can create tests, set goals and read results. You can sign in to the web admin too.
Nothing to host
Cloud runs on Cloudflare. There is no WordPress, server or plugin to install and keep updated.
How it works
Sign up with two fields
Enter an email and your domain. You get the script, an API key and the MCP details straight away.
Ask for a test
Tell your agent what to change and what counts as a conversion. Or have it give you a link to the point-and-click editor and make the change on your own page.
Ship the winner
Results are checked every 15 minutes and get a Bayesian verdict. Each test can just report the winner, show it to everyone, shift traffic to the leader, or auto-optimize its copy round after round.
Also included
Sites that are not WordPress
Static HTML, Webflow, Framer, Shopify, Next.js and Astro. On WordPress, use the plugin: self-hosted traffic is never metered.
Heatmaps and session replay
Turn on journeys for a site to record clicks, scroll depth and sessions. Your agent can read them, or give you a link to watch them.
Results by audience
Every site starts with audiences for Google Search, Google Ads, Meta Ads, email and AI assistants. Each gets its own breakdown and verdict.
Get started
Go to cloud.absplittest.com and enter your email and domain, or tell your agent: “Sign us up at cloud.absplittest.com.” Until you confirm your email, Cloud records your first 100 visitors. After that you have 100,000 MTUs free. An MTU is one visitor tested or recorded in a month.
Teams Yearly and Teams Lifetime licences include Cloud MTUs. Add your licence key when you sign up. See pricing.

Test anything in WordPress.
Blocks, pages, posts, page-builder elements, custom post types, templates, shortcodes, HTML, JavaScript, or CSS.
All of it works without workarounds.
The most conversion options
Page visits, clicks, form submits, purchases, active time, scroll depth, JavaScript events, conversion pixels, block or module triggers, and server-side PHP or AJAX actions. We currently support 11 conversion (goal) types.
Point-and-click testing
Click the element you want to improve, review the AI variations, make your edits, and start the test, all without a developer.
Blocks, Bricks, Beaver Builder,
Elementor, Breakdance and more
Deep integration with your page builder means you can test blocks, elements, sections, templates and layout parts without leaving your workflow.
Autocomplete
Calculates when enough data has been collected, then automatically shows the best variation to all. We do the Bayesian statistics calculations, so you don't have to.
Auto-optimize
A winning magic test builds its own next round. The winner becomes the control and AI writes new variations to beat it.
Privacy (GDPR) friendly
We do not store any user identifying data or utilize remote servers for customer data.
Cookie consent tools are respected, so no data transmitted or saved until accepted.
Unlimited Tests, Variations & Goals
Create as many tests as you like with as many test variations as you want.
Unlimited Page Views
Collect as much data as you need to make an informed decision without worrying about credits or usage limits.
Test inside templates, parts and block layouts
Whether you use Block Templates, Beaver Themer, Elementor Templates, Bricks, Breakdance or another theme builder, you can test headers, footers, sections and layout parts directly.
A.I assistant
Our Conversion Rate Optimization Agent scans your site to understand your business & tone, then creates tests for you.
Cache friendly
We prerender your test variations hidden, then use JavaScript to show the appropriate test variation.
You can use full page caches, object caches, pre-rendered cloudflare caches or whatever you like.
External conversions with fingerprint pixels.
Remote cookies no longer work reliably, so we use fingerprinting instead.
Paste our conversion script on your conversion pages, on any domain. The script connects test visitors to conversions, no matter where they end up.
Multiple conversions - subgoals
See how your tests affect other metrics, and analyze your funnel before you decide.
Order Value Optimization
WooCommerce, SureCart, Easy Digital Downloads, Memberpress and more. Optimize for revenue, not only clicks and views.
Analytics integrations
Tag users when they see a test and when they convert. Then you can view your funnel inside your analytics apps.
Dynamic Traffic Allocation: optimize traffic to the winning variation on the fly. Reduce visits to losing variations whilst maintaining significance.
Test Time Remaining
Estimates based on incoming data how long it will take for your test to reach statistical significance.
Webhooks
Send an HTTP POST whenever a test is created or completed, so your external systems stay in sync.
Link To Variation
Create your test, then generate direct links to each variation. You can also force specific visitors to view a particular variation.
Test Ideas
Plan and prioritize your split tests. Score each idea by Impact, Reach, Confidence and Effort and the highest scores rise to the top.
Continuous learning
Every finished test is recorded. AB Split Test finds why it won or lost and what to try next.
Session recordings
Watch real user sessions to see where visitors hit friction or get confused, which you'd never spot in the data alone.
API/MCP/CLI
Control your A/B tests from AI assistants, CI/CD pipelines, or custom applications, so testing fits into the workflow you already have.
Cross-Domain Split Testing
Register an external domain, generate a lightweight tracking script, and serve the correct test variation to visitors on Shopify, HubSpot, or any external platform. Conversion events sync back to your WordPress dashboard automatically.
Cloudflare Workers Integration
Run full-page split tests at the network edge. Variations are served under your original URL with no redirect, flicker, or URL change, so your ads and SEO are unaffected.
Split Test Server
Run split tests on any platform and still control the data. Full-page, code and point-and-click tests, heatmaps and session replays, all from one snippet. Your own visual website optimizer.
