Components are the basic building block of UIs. In modern view layers like React, Vue, and Angular developers build complex UIs out of simple components. Chroma’s mission is to make UI component development organized, repeatable, and satisfying. We're creating a world where developing app UIs is as easy as Lego.
We maintain Storybook 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, an industrial-grade visual testing service for UI components and libraries made for Storybook. It's used by Adobe, BBC, Salesforce, Zenefits and Storybook itself.
We’re open source veterans who believe that important innovations start with open source. Previously, we helped launch widely-loved Apollo GraphQL, an application data layer adopted by the biggest tech companies on the planet including GitHub and Airbnb.
