The Challenge

Documentation Friction

Setting up Swagger UI or Redoc often requires server-side configuration or build steps. Developers just want to paste a URL and see the docs instantly.

CORS Issues

Testing APIs from a browser-based documentation tool is often blocked by CORS policies, making “Try it out” buttons useless without backend changes.


The Solution

Dynamic Rendering Engine

Built a parser that fetches any valid openapi.json URL and renders a responsive, beautiful documentation interface on the fly without any build step.

Built-in CORS Proxy

Included a lightweight proxy middleware in Next.js to route API requests, bypassing browser CORS restrictions and allowing developers to test endpoints seamlessly.

Developer Experience First

Focused on a clean, distraction-free UI with comprehensive request/response schema visualization and authentication helper (Bearer/API Key).
