Start with a diff
Open a pull request. Diffraction uses the changes and your project’s context to plan what needs a closer look.
UI review for every pull request
Catch visual bugs, broken funnels, and hidden buttons before your users do.
A clearer view of how your changes look and behave. Find the details that code review can’t show you.
A second pair of eyes
Look beyond
the code.
A button hidden on a small screen. A flow that no longer feels right. Diffraction reviews the changed experience and brings the evidence back to your pull request.

What does Diffraction review?
Diffraction reviews how web applications look and behave after a code change. It follows relevant user flows and looks for visual and interaction regressions, called aberrations.
Does it work with our existing tests?
Yes. Existing end-to-end tests provide useful context and reusable coverage. Diffraction adds a context-aware review of the experience around the proposed changes.
Where can I see the evidence?
The review links back to recorded browser steps, screenshots and replay evidence. Each browser and viewport gets its own recording, so the evidence reflects what was actually tested.
