The Challenge

Documentation Friction

Standard Swagger/OpenAPI installations often suffer from broken UI or expired authentication tokens exactly when they are needed for client reviews.

CORS & Proxy Issues

Testing APIs from a browser is often blocked by CORS policies, making interactive consoles useless without tedious backend configurations.


The Solution

Auto-Discovery Engine

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

Built-in CORS Proxy

Included a lightweight proxy middleware to route requests server-side, bypassing browser restrictions and allowing “Try It” to work reliably.

Interaction Focused

Focused on an ultra-clean UI with comprehensive schema visualization and an authentication manager for Bearer tokens and API Keys.
