Where Storybook teams benefit

Component story prep

Populate every component variant and state with labeled placeholders, eliminating the need for final assets during development.

Chromatic stability

Create reproducible baselines by using identical placeholder packs across all Chromatic builds and screenshot comparisons.

Theme & state coverage

Use per-item color overrides to demonstrate light, dark, success, pending, and error states in your component documentation.

Design system alignment

Share the preset with designers and PMs so everyone's Storybook builds use the same branded colors and aspect ratios.

Set up in three steps

  1. 1

    Load the Storybook preset

    Use the Storybook preset to instantly populate hero, card, widget, and state component sizes—or paste your own dimensions.

  2. 2

    Customize with component names

    Add aliases and color overrides to tag placeholders by component and state—everything updates live in the preview.

  3. 3

    Commit & sync stories

    Download the PNG, SVG, or WebP ZIP and commit it to your repo. Update every Storybook story with the same pack for consistent baselines.

Storybook FAQ

How do I use this with Chromatic?
Generate your placeholder pack and commit the ZIP to your repo. Use the images in your Storybook stories and Chromatic will capture consistent visual baselines.
Can I apply component-specific customizations?
Yes. Use the alias field to tag placeholders by component name, and add color overrides to highlight different states or themes within the same pack.
What about design system updates?
Regenerate the pack with new colors or sizes whenever your design system evolves, then replace the ZIP in your repo to keep all stories in sync.
