Hi, we're Chroma. We build tools to help frontend developers build, test, and share UI components. We maintain [Storybook](https://storybook.js.org/), the most popular open source tool for developing UI components. It’s used by thousands of companies like Lyft, Airbnb, and GitHub to engineer UIs for millions of people. Chroma is run by Storybook core maintainers. We speak at conferences, write books, articles, and tutorials related to Component-Driven Development using Storybook. To fuel our open source and community work we make [Chromatic](https://www.chromaticqa.com/), an industrial-grade visual testing service for UI components and libraries made for Storybook.
