Storybook

The industry-standard frontend workshop for building, documenting, and testing UI components in isolation.

Storybook serves as a dedicated development environment for UI engineering, supporting frameworks like React, Vue, and Angular. By decoupling components from application logic and data APIs, it allows developers to build complex interfaces (like a high-fidelity data table or a multi-step checkout form) without spinning up the entire stack. It integrates directly with Chromatic for visual regression testing and exports a living documentation site that syncs design tokens with production code.
