crxpay

A/B testing

Two paywalls walk in. One walks out.

Ship two versions of your paywall. crxpay splits traffic 50/50, watches the conversion rate, and picks the winner when the numbers are clear. You do nothing. New users just see the better one.

How it works

Four clicks from hunch to proof.

You do not need a stats degree. crxpay handles sample size, split traffic, and the math. You just pick what to test.

01
Make two paywalls

Duplicate your existing paywall. Change a headline, a price, a button color. Anything you want to try.

02
Hit "run test"

crxpay splits new users 50/50 between A and B. Existing users keep whatever they already saw.

03
Let the numbers cook

Watch conversions climb for each variant. We show you if the gap is real or just luck.

04
Ship the winner — no Web Store update

Every variant lives in the dashboard. Promote the winner with one click; new users see it on their next paywall load. Your extension stays untouched in the Chrome Web Store.

How it's built

Tiny tweaks. No re-submission.

Every paywall variant lives in your crxpay dashboard. Your extension stays untouched in the Chrome Web Store while you iterate on price, copy, and design.

What we don't promise

A/B testing needs traffic. With ~100 weekly checkout views, expect 4–6 weeks to call a tight-margin winner. With ~1,000 weekly views, days. The dashboard tells you in plain English when you have enough data to act — not a moment sooner.

Run portfolio experiments across multiple extensions to hit significance faster. We'll always show the credible interval, not just the point estimate.
