Test every change. Keep what wins.

How it works

Your numbers pick the test.

1. 01

   You type it

   One command in Claude Code, or ask Codex what to test.

2. 02

   Your agent builds the test

   It proposes three changes with the numbers behind each, sizes the one you pick from your traffic, and builds it in your code.

3. 03

   You merge, then keep the winner

   Merge to start the test. When the answer is in, one more pull request makes the winner your page.

What you get

From idea to winner, in your code.

• Ideas with evidence

  Each change comes with the numbers from your own pages behind it: visits, how many stay, how many sign up.

• Sized before it starts

  How many visitors each version needs, and how many weeks that takes at your traffic.

• Every visitor counts

  Visitors are split with nothing stored in their browser, so everyone who lands is in the test.

• A straight answer

  The chance the new version beats your page, and by how much. A winner only when the numbers say so.

• The winner shipped

  One pull request makes the winner your page's only version and takes the test code out.

• Free, on your own analytics

  Tests read Shipfound's free analytics. Not on your site yet? Your agent adds them first, as one pull request.
