Shumway SEO Toolkit par Brian Shumway

Shumway SEO Toolkit is a local-first Firefox extension for page-level inspection. It gives SEOs, product managers, content teams, and developers a structured workspace for the current page, with no accounts, no analytics, no tracking pixels, and no background crawling.

Open the toolkit on any page to inspect rendered metadata, indexability signals, headings, links, images, structured data, social metadata, page styles, lightweight performance signals, accessibility structure, SERP previews, robots.txt behavior, and webmaster-tool shortcuts.

All exports are generated locally in your browser. Save page data as CSV, TSV, JSON, Markdown, image ZIP files, accessibility JSON, or SERP preview images.
