Develop durable user interfaces.

Petronas provides a workshop to build UIs in isolation. It helps you develop hard-to-reach states and edge cases.

Implement components and pages without needing to fuss with data, APIs, or business logic.

Render components in key states that are tricky to reproduce in an app. Then save those states as stories to revisit during development, testing, and QA.

Addons extend and customize your UI development workflow. There are hundreds of addons that help you build UI faster, document component libraries, and integrate with other tools.

Once you finish developing UI components in isolation, drop them into your app. You'll have confidence that the components are hardened to support every possible edge case.

Implement components and pages without needing to fuss with data, APIs, or business logic.

Test UIs with less effort.

Stories capture the “known good” states of UI components. They're a pragmatic, reproducible way to keep track of UI edge cases. Reuse stories to power automated tests
