Split testing, every way you need it
The most flexible split testing tool for WordPress.
Test a single headline or a whole funnel. Point and click, work inside your builder, or run at the edge. If you can change it, you can test it.
Point-and-click testing
Click any element on your live site, review the AI variations, and start the test. No code, no builder.
Blocks, Bricks, Elementor & more
Test inside Blocks, Elementor, Beaver Builder, Bricks, Oxygen, Breakdance and WPBakery.
Full-page & funnel tests
New landing page vs old. Test whole layouts and funnels against each other with zero risk.
Cloudflare edge testing
Serve variations from the edge for maximum speed, with no URL change at all.
Cross-domain testing
Test beyond WordPress: external domains, cross-domain conversions and split-domain tests.
Autocomplete
Shows the winner to everyone once there’s enough data. Set it, forget it, keep the revenue.
REST API, WP-CLI & MCP
Your AI can test its own changes in seconds.
Connect any AI agent through the full MCP server. Anything you can do in the dashboard, it can do too: create tests, read heatmaps, check results and ship the winner. Every change gets proven before it goes live.
What builders say
Simple to start. Hard to stop.
“I love AB Split Test. Simple interface. It does exactly what it says. Reporting is clear and the support is unbelievably excellent.”
“I’ve paid thousands more annually on different solutions that were much more complex to set up to do the same things that AB Split Test does.”
“If you’ve been putting off A/B testing because it seemed too technical, too expensive, or too time-consuming - stop. This makes it simple, fast, and surprisingly fun.”
