AB Split Test Cloud
Split testing & conversion optimization for every other site
Test improvements on any site, no WordPress required
One script tag on your static site, Next.js, Astro, Webflow or Framer build. The same tests, Bayesian statistics, heatmaps and session replays our WordPress customers have used since 2018. No dashboard to learn: tell Claude, ChatGPT, Cursor or any MCP client what to test, and it creates the test, reads the verdict and applies the winner.

Build with your favorite AI agent
Let your agent install it
Paste this into Claude, ChatGPT, Cursor, Hermes or any agent that speaks MCP:
Set up AB Split Test Cloud on this site. Connect to the MCP server at https://cloud.absplittest.com/mcp using my API key (ask me for it). Call create_site with my domain and add the script tag it returns 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.
How it works
Three steps from script tag to winner
No account dashboard, no onboarding calls. One snippet, one conversation, one answer.
Paste one script tag
Add the snippet for your site to your template, your tag manager or your framework layout. Visits, clicks and conversions start arriving at cloud.absplittest.com straight away. Nothing to install, no build step.
Create a test
Ask your AI agent to set it up over MCP, or open the point-and-click editor on your live page, change a headline or a button, and save. Full-page, visual, CSS and on-page variants are all supported.
Read the verdict, apply the winner
Results come back as plain answers: which variation is most likely best, how much you risk by picking it, and how long until it is safe to call. Apply the winner yourself, or let the test do it the moment the statistics allow.
Everything included
The same testing system, minus the WordPress
Every feature below is in the free allowance. Nothing is held back for a paid tier.
Four test types
Full-page redirect tests for whole-page redesigns. Point-and-click edits for headlines, buttons and images. CSS variations for restyling. On-page variants for markup you control yourself.
Goals that match the business
Count clicks, visits to a URL, custom JavaScript events and revenue per visit. Add sub-goals to see how a test moves the rest of the funnel before you call it.
Statistics you can act on
The plugin’s Bayesian engine, ported line for line. Probability to be best, expected loss, minimum conversions, projected duration - and a plain “blocked by” reason whenever it is too early to decide.
Winning modes
Choose what happens when a verdict is in. Report it and wait for you. Declare the winner and send everyone to it. Keep running and shift traffic toward the likely winner with Thompson sampling. Or auto-optimise: declare, hand the result to your agent, and start the next round.
Point-and-click visual editor
Open a one-time editor link on your live page, click the element you would change, edit it and save. The test is created for you, and your agent sees it immediately. No builder, no code, no copied pages.
Heatmaps, page analytics, session replay
See where visitors click, how far they scroll and where they hesitate, then watch the sessions behind the numbers. Agents can read the same click maps and scroll data to decide what to test next.
MCP for agents
One MCP endpoint with tools to create sites and tests, read results, set winners and fetch heatmap data. Every call is audited. Works with Claude, ChatGPT, Cursor and any client that speaks MCP.
Built on Cloudflare
The script, collector and statistics run on Cloudflare Workers, Durable Objects and D1, close to your visitors. Your site’s performance does not depend on our origin server, because there isn’t one.
Any site that can add a script tag
Webflow, Framer, Next.js, Astro, Hugo, Shopify themes, hand-written HTML. If you can add a script tag, you can run a test. One account covers several sites and shares one allowance.
One script tag. No card, no time limit.
For AI agents
The agent is the UI
Connect your MCP client to cloud.absplittest.com with your API key and the whole product is available as tools. A typical session looks like this.
You tell Claude: “Register example.com and give me the snippet.” It calls create_site and hands back the script tag. You paste it and say: “Run a full-page test of /pricing against /pricing-b, goal is a click on Start trial, mode winner.” It calls create_test and the test is live for the next visitor. A week later you ask: “How is the pricing test doing?” It calls get_results and tells you, in words, that variation B has a 96 percent probability of being best with an expected loss under half a percent, and asks whether to apply it. You say yes, it calls set_winner, and every visitor now sees /pricing-b.
Agents also get the data humans get: click maps, scroll depth and session events as JSON, so an agent can look at a heatmap, propose the next test and build it in the same conversation. Results use the same fields as the WordPress plugin’s MCP tools, so an agent that already knows one knows both.
Already on WordPress?
Keep your plugin. AB Split Test for WordPress stays self-hosted, unmetered and fully supported, and nothing about your licence changes. Cloud is for the sites the plugin cannot reach: static builds, framework apps, hosted site builders and projects run entirely by an agent. If you have both, they run side by side.
Questions
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 counts as a page view?
Every page load where the script runs, on any site in your account, counts as one page view. One account with three sites shares one allowance. Clicks, conversions and heatmap events do not count separately.
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 you move to a paid plan. Pricing is coming soon; join the waitlist below and we will tell you first.
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 will be available before paid plans launch. 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.
