OpenAPI Swaggerizer

About

The OpenAPI Swaggerizer is a lightweight, high-performance utility designed for developers who are tired of navigating raw JSON files. It instantly transforms messy, unformatted OpenAPI JSON pages into a professional, structured, and interactive visual interface.

Whether you are working on localhost or browsing public API docs, this extension automatically detects the schema and handles the organization for you, allowing you to focus on integration rather than deciphering brackets.

✨ KEY FEATURES:

Hierarchical Grouping: Automatically organizes endpoints by Tags, then groups them by Root Path and Sub-resources. It turns a flat list of routes into a logical, navigable tree.

Instant UI Injection: Using a smart MutationObserver, the extension detects OpenAPI schemas in real-time and injects a clean dashboard directly into the page, replacing the browser's default text viewer.

Deep Endpoint Mapping: View methods (GET, POST, PUT, DELETE) with color-coded badges, operation IDs, summaries, and full descriptions at a glance.

Parameter & Response Tables: Explore request requirements and response status codes with dedicated tables showing data types and "required" flags.

Sticky Sidebar Navigation: Jump between different tags instantly using a sidebar that supports smooth-scrolling and active-state highlighting.

Developer Optimized: Built with vanilla JS to ensure zero latency and high performance, even when rendering massive JSON payloads with complex path structures.

🔒 100% PRIVACY-FOCUSED & SECURE:
Your API specifications—especially internal or local ones—are sensitive. This extension runs entirely locally in your browser. It reads the DOM (HTML structure) of the current tab to perform the transformation in-memory. No data is collected, stored, or sent to any external servers.
