AB Split Test Cloud
Split test any website. Let your AI agent run it.
One script tag on your static site, Next.js, Astro, Webflow, Framer or Shopify theme. The same visual editor, Bayesian statistics, heatmaps and session replays our WordPress customers have used since 2018, with no WordPress anywhere.
No card, no time limit. 25,000 monthly tracked users included with your AB Split Test plan.
Let your agent install it
Copy one prompt into Claude, ChatGPT, Cursor, Hermes or any agent that speaks MCP. It signs you up, adds the script tag and asks you what to test.
Set up AB Split Test Cloud on this site. If I don’t have an account yet, sign me up at https://cloud.absplittest.com with my email and this site’s domain; that gives you the script tag and an API key. Connect to the MCP server at https://cloud.absplittest.com/mcp with the API key. If list_sites doesn’t show my domain, call create_site with it. Add the script tag to the main layout so it loads on every page. Show me the change before you deploy it, then ask me which conversion goal matters most before you create the first test.
Know when you have a winner
Every 15 minutes the Bayesian engine from the WordPress plugin works out each version’s probability of being best, its lift against the original and what it is worth over a year. When it is too early, it says why.
- Probability to be best, uplift and expected loss
- Breakdown by device and by audience
- Show the winner to everyone, or shift traffic to it as you go
See where people click, and where they give up
Click and scroll maps are drawn over your live page, per screen size. Rage clicks and dead clicks stand out, so the next test is obvious.
- Clicks, scroll depth and engaged time
- Rage and dead clicks per element
- Filter by test version, source or device
Watch the visits behind the numbers
Replay a single visitor’s path through your site: every page, every click, and which version of each test they saw. Jump straight to the sessions that converted, or the ones that stalled.
- Pages, clicks and timing for each visit
- The test version each visitor saw
- Kept 90 days by default, shorter if you choose
Every page, measured
Engagement, scroll depth, exits and later conversions for each page, with the most clicked elements and where visitors came from.
- Most clicked elements, with rage and dead clicks
- Referrers and UTM sources
- Where visitors went next
A dashboard if you want one. An agent if you don’t.
Every test, verdict and winner is in a clean admin area. The same actions are MCP tools, so your agent can create tests, read results and apply winners without you opening it.
- Running, complete and draft tests at a glance
- Report only, show the winner, or shift traffic
- Share a read-only results link with a client
Three steps from script tag to winner
Paste one script tag
Add the snippet to your template, tag manager or framework layout. Visits, clicks and conversions start arriving straight away.
Create a test
Ask your agent over MCP, or open the point-and-click editor on your live page, change a headline or a button, and save.
Read the verdict, apply the winner
Results come back as plain answers. Apply the winner yourself, or let the test do it the moment the statistics allow.
The same testing system, minus the WordPress
Four test types
Full-page redirect tests, point-and-click edits, CSS variations and on-page variants for markup you control.
Goals that match the business
Clicks, visits to a URL, custom JavaScript events and revenue per visit, with sub-goals for the rest of the funnel.
Winning modes
Report and wait, show the winner to everyone, shift traffic to the leader, or auto-optimise round after round.
MCP for agents
One endpoint with tools to create sites and tests, read results, set winners and fetch heatmap data. Every call is audited.
Built on Cloudflare
The script, collector and statistics run on Cloudflare’s network, close to your visitors.

Frequently asked
Short answers. Ask us anything else on the contact page.
Do I need WordPress?
No. Cloud runs entirely from one script tag and the cloud.absplittest.com service. WordPress is not involved at any point.
What happens after 100,000 page views?
The free allowance is 100,000 page views, once, with no clock running. We tell you at 80 percent and at 100 percent. Past the allowance your script keeps being served and running tests do not break, but results stop updating until your account is on a plan. Your AB Split Test plan includes 25,000 monthly tracked users, and Cloud 500,000 raises that to 500,000 for $1,999 a year.
Where is my data stored?
On Cloudflare’s network, in our account. Test configuration and counts live in Cloudflare D1 and Durable Objects; heatmap and replay recordings are kept for 90 days by default, and you can shorten that per site.
Is it GDPR-ready?
Cloud is a hosted service, so unlike the WordPress plugin it is a processor you declare, with Cloudflare as our sub-processor. Visitors are identified by an anonymous first-party cookie, we do not collect names or email addresses, and recordings expire automatically. A data processing agreement is available on request. Please check with your own adviser for your situation.
Can I use it with Webflow, Framer, Next.js or Astro?
Yes. Any site that can add a script tag works, including hosted builders, static generators, framework apps and plain HTML. The snippet tool gives you install notes for your platform.
Does it slow my site down?
The script is served from Cloudflare’s edge, cached, and only loads the configuration for your site. Visual and CSS tests hide the page for a fraction of a second until the right variation is applied, so visitors never see a flicker.
Run your first test this week
