Deterministic Storybook stories

Stop story diffs that come back changed without a real change.

StorybookDeterminismFlake

What it does

Focuses only on the run-to-run variation the capturer cannot neutralize from outside your app: the clock, infinite JS animations, live data, and non-Math.random randomness. It deliberately skips what UI Verify already handles for you.

Run it when a story diffs every run for no real reason.

Pins the sources of flake a story owns, so a red build means a real change.
Leaves the flake classes the capturer already kills alone, no busywork.
Narrow by design: story isolation removes most of the hard cases for free.
