Storybook & Chromatic

Migrate in one line.

Same Storybook build.
Transparent pricing.

Replace one action in your CI workflow. Your existing Storybook build stays untouched — pxdiff captures it, diffs it, and posts results to your pull request. No vendor lock-in, no per-seat fees.

Your AI agent can see what changed.

Coding agents run tests, but can't see visual regressions. pxdiff gives them eyes — diffs they can read, approve, or fix without waiting for a human.
