Swagger Preview for Notion

About

Swagger Preview for Notion

Instantly preview OpenAPI and Swagger specifications written in Notion code blocks — no copy-pasting into external tools required.

HOW IT WORKS
1. Open any Notion page that contains a code block with an OpenAPI/Swagger spec (YAML or JSON).
2. The extension automatically detects the spec and shows an "API Preview" button on the code block.
3. Click the button to open an interactive Swagger UI panel on the right side of the page.

FEATURES
• Automatic detection — Recognizes OpenAPI 3.x and Swagger 2.0 specs in both YAML and JSON format.
• Interactive Swagger UI — Browse endpoints, view schemas, and use "Try it out" to send live API requests.
• Resizable panel — Drag the edge to adjust the panel width, or switch to fullscreen.
• Popup controls — Rescan the page or close the panel from the toolbar popup.
• Lightweight — Runs only on notion.so pages. No data is collected or sent to any server.

PERMISSIONS
This extension requests minimal permissions:
• activeTab — Used only to check whether the current tab is a Notion page.
• Content scripts run exclusively on notion.so.
• No background processes. No host permissions. No data collection.
