Feature
Split Test Server
Run your split tests on any platform and still control the data. One snippet turns your WordPress install into the testing server for sites that have nothing to do with WordPress: your own visual website optimizer, on your own hosting, and a plan for all those vibe-coded sites.
One Install, Any Site
Add the domain under Settings > Tracking & Privacy > External Domain Testing, copy the snippet it generates, and paste it into the <head> of your site. Shopify, Webflow, Squarespace, HubSpot, Astro, Next.js or something hand-rolled - if you can add a script tag, it can be tested. One snippet covers every page on that domain.
The Whole Suite, Not Just Redirects
Full-page tests, code (CSS) tests, on-page tests and point-and-click Magic tests all run through that one snippet - along with targeting rules, audiences, device and referrer conditions, traffic allocation and autocomplete. It is the same testing engine your WordPress pages use, pointed somewhere else.
Point and Click on a Site You Did Not Build
Launch the Magic editor straight onto an external page from your domain list. Click a headline, retype it, save - the snippet serves the variation from then on. No access to the other site’s codebase, no developer, no deploy.
Heatmaps, Page Analytics and Session Replays
Switch on journey capture and every tracked external page feeds the same Heatmaps, Page Analytics and Session Replays screens as your WordPress pages, identified by URL. Clicks, rage clicks, scroll depth, engagement time and full session playback - from a site you do not host.
A Plan for Your Vibe-Coded Sites
The landing page you generated in an afternoon has no analytics story and nothing to test with. Paste the snippet into its head and it gets heatmaps, session replays and real split tests without you touching a line of the generated code - or regenerating it and losing the lot. The same applies to every client microsite and campaign page living outside your WordPress build.
Your Own Visual Website Optimizer
Hosted optimization platforms charge by tested visitor and by seat, and keep your results on their servers. Run the same job from an install you already pay for: unlimited tested visitors, no seats, and White Label so clients see your brand rather than ours. One install per client, provisioned with a single command.
Revenue Goals That Work Off WordPress
WooCommerce and Easy Digital Downloads goals need WordPress, but order value does not. The snippet reads the order total from the thank-you page on its own - known URL parameters, common order-total markup, or the visible “Order total” line - and where a checkout is unusual, one line of JavaScript sets it exactly. Order Value Optimization then picks the variation that earns the most, not simply the one that converts most often.
You Control the Data
Nothing leaves your install. No third-party analytics account, no per-visitor pricing, no data-processing agreement to sign. Read it however suits you: the results dashboard, the REST API, MCP so an AI assistant can query your tests directly, or WP-CLI.

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.

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.
Privacy (GDPR) friendly

Cookie consent tools are respected, so no data transmitted or saved until accepted.

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.
No remote cookies or servers
We only use local cookies & anonymously identify your users. Nothing invasive or over-reaching here.
A.I assistant
Our Conversion Rate Optimization Agent scans your site to understand your business & tone then creates winning tests for you in seconds.
Cache friendly
We prerender your test variations hidden, then use ultra snappy JS 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 are dead, so we've implemented fingerprinting.
Paste our conversion script on your conversion pages, on any domain. Our clever script will connect test visitors to conversions, no matter where they end up.
Multiple conversions - subgoals
See how your tests affect other key metrics. Analyze your funnel to make the most informed decisions.
Order Value Optimization
WooCommerce, SureCart, Easy Digital Downloads, Memberpress and more. Dont just optimize clicks and views, but revenue.
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.
Session recordings
Watch real user sessions to discover friction points, confusion, and conversion opportunities you'd never find in the data alone.
API/MCP/CLI
Control your A/B tests from anywhere - AI assistants, CI/CD pipelines, or custom applications. Build testing into your workflow, not around it.
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.
