The expensive part is already done
You paid for the click. Then you guessed what to show it.
Ads, SEO and content get people to your site. What they see when they land decides whether that spend comes back. Most teams never measure it.
02
Every idea waits on a developer
A new button label becomes a ticket, a sprint and a deploy. Two weeks pass before a single visitor sees it.
03
Enterprise tools price you out
Annual contracts, sales calls and an implementation project, all before your first test goes live.
ExperimentHQ replaces the guess with a number.
Do the math on your own numbers

Same traffic, same ad spend. Drag the sliders and see what a better-converting page adds to your revenue.

Why teams switch
Enterprise testing power, minus the enterprise.
Most A/B testing suites were built for companies with an experimentation department and a six-figure software budget. ExperimentHQ is built for teams that want to test a headline this afternoon.

Why we built it
We tried Optimizely. Too expensive. We tried VWO. Too complex. We tried Google Optimize. Shut down.
A/B testing tools were built for Fortune 500 companies with experimentation teams and months of implementation time. Most teams just want to test a headline and see if it converts better. We believe every team should be able to run experiments, not just those with enterprise budgets.

What is A/B testing?
A/B testing (also called split testing) compares two versions of a page to see which one performs better. Half of your visitors see the original, half see the variant, and you measure which version gets more of them to convert. ExperimentHQ lets you run those tests without writing code.
How long does it take to set up ExperimentHQ?
About 2 minutes. Add one script tag to your website, then create your first experiment in the visual editor. There is no implementation project and no sales call.
Do I need a developer?
Only to paste the script once, and on Shopify, WordPress or Webflow you can usually do that yourself. After that, anyone on the team can change headlines, images, buttons and layout by clicking on the page.
Will it slow down my website?
The script is about 5KB gzipped and loads asynchronously, so it never blocks your page from rendering. It also works on single-page apps built with React, Vue or Next.js.
How much does ExperimentHQ cost?
The Free plan includes 10,000 monthly visitors, 3 experiments and 1 domain. Pro is $99 per month for 50,000 monthly visitors, unlimited experiments and 3 domains. Scale is $499 per month with unlimited visitors and domains. Annual billing saves 17%.
Is there a guarantee?
Yes. Paid plans come with a 14-day money-back guarantee for first-time subscribers, and you can cancel anytime. The Free plan needs no credit card.
How do I know when a test has a winner?
Every experiment shows the conversion rate of each variant with a statistical significance indicator. When the data is strong enough, ExperimentHQ marks the winner so you know it is safe to roll out.
Which platforms does it work with?
Any website where you can add a script tag, including Shopify, WordPress, WooCommerce, Webflow, Framer, Wix, Squarespace, Next.js, Nuxt and React.
