Installation

This extension requires the Lighthouse CLI to be installed globally:

npm install -g lighthouse

Lighthouse also requires a Chromium-based browser (Chrome, Edge, Brave, etc.) installed on your system.

Usage

1. Open Raycast and search for "SEO Lighthouse"
2. Enter the URL you want to audit
3. Select device mode (Mobile/Desktop) and categories
4. Optionally use Choose Output Directory to pick where JSON reports are saved
5. Press Enter to run the audit
6. View the report with scores, metrics, and opportunities
7. Use Cmd+Shift+C to copy the scorecard image, Cmd+I for AI insights, Cmd+D for detailed field descriptions

JSON reports are saved to the Output Path as lighthouse-<host>-<timestamp>.json and are not deleted. A 24-hour cache is stored separately in the extension support folder so re-running the same URL/device/categories is fast without wiping yesterday's report.
