Your code review agent says “done.” Your customer says “broken.”

Coding agents outpace testing, even with AI review. RunStory runs your software like a human and sends defects back to your agent before customers find them.

Join the RunStory alpha

RunStory checks that your software does what you meant.

It uses your software.
It runs your software in a separate environment, tries relevant workflows, and checks the results. You keep working.
Reports failures.
Your coding agent receives the actions RunStory took and evidence of the unexpected result.
And verifies the fix.
After your agent makes the change, RunStory repeats the failing workflow to check that the problem is resolved.

Illustrative example

A bug AI code review can miss.

You prompted

“Let customers edit their delivery address during checkout.”

The address saved, but the basket emptied. RunStory catches the failure by running the full customer journey.

1. It uses your software.: RunStory adds items to the basket, starts checkout, changes the address, and continues.
2. Reports failures.: The address saved, but the basket emptied. Your coding agent receives the steps and evidence of the missing items.
3. And verifies the fix.: After your agent’s fix, RunStory repeats the journey and checks that the address changes and the basket stays intact.
