Is UI Parity AI-powered?

UI Parity uses AI to help agents understand your design system's context. However, the verification itself relies on measured values rather than AI, ensuring deterministic and consistent results. AI assists but never replaces the actual drift detection.

Do I have to map stories to Figma myself?

No. UI Parity auto-maps every story to its Figma variant. Only the uncertain ones are flagged for your review and one-click confirmation.

Do I need to change my stories?

No. UI Parity works with the stories you already have without requiring any modifications to your existing Storybook setup.

What does 'not compared' mean?

When several Figma variants fit a story or none fit, UI Parity marks it as 'not compared' and explains why, rather than guessing or forcing a match.

A Storybook addon that measures how much of your design system is actually in code and whether it matches your Figma designs, with coverage, parity and drift

What it is

Screenshot of the UI Parity homepage — uiparity.com, as visitors see it

UI Parity is a Storybook addon that validates UI components by comparing what renders against Figma designs. It measures coverage (how much of the library was checked), parity (how much matches the design), and drift (which components differ), showing exact differences in color, typography, spacing, part sizes and part gaps.

The tool works without dashboards or context switches, integrating as a panel tab in Storybook. It auto-maps stories to Figma variants, flags uncertain matches for manual confirmation, and presents findings deterministically without guessing. Each drift item displays the Figma value next to the rendered one for easy comparison.

UI Parity runs on the whole library in minutes and lists every story that wasn't checked with its reason. It uses measured values rather than AI for verdicts, ensuring the same story produces the same answer every run. The tool is free to install and use with paid plans available for additional reviews.
