What RapiDoc is

RapiDoc is a responsive web component that turns OpenAPI and Swagger specifications into interactive API documentation. It supports OpenAPI 3.0.x and 3.1.x, plus Swagger 2.0, and includes a console for calling and testing APIs from the documentation. Presentation options include dark and light themes, brand colors, typography, logos, header styling, and read, view, or focused rendering. Models and examples expand by default, request fields are pre-populated, and request and response views can appear side by side. RapiDoc works with plain HTML and frameworks including React, Vue, Angular, Svelte, and Lit. The component can be loaded as a JavaScript module from unpkg, and its core package is published on npm. The project also documents building the bundle and deploying its documentation site to GitHub Pages. The software is MIT-licensed and listed as free, with no paid plan or usage limits stated. WCAG 2.1 compliance enhancements are on the roadmap; current compliance is not claimed.
