# storybook vs swagger-ui

storybook and swagger-ui share 6 technologies: React, TanStack, react-inspector, react-syntax-highlighter, js-yaml, and prop-types. storybook is written in TypeScript and swagger-ui in JavaScript.

- [storybookjs/storybook](https://seerepo.com/r/storybookjs/storybook): Storybook is the industry standard workshop for building, documenting, and testing UI components in isolation
- [swagger-api/swagger-ui](https://seerepo.com/r/swagger-api/swagger-ui): Swagger UI is a collection of HTML, JavaScript, and CSS assets that dynamically generate beautiful documentation from a Swagger-compliant API.
