Shumway SEO Toolkit

Shumway SEO Toolkit is a fast, private, local-first browser extension for folks who need on-page data without juggling multiple extensions and developer tools. Inspect metadata, schema, headings, links, images, HTTP trace, SERP previews, robots.txt, accessibility tree, webmaster shortcuts, and flexible exports in one workspace. It runs from your active tab, with no accounts, tracking, telemetry, or server-side uploads. Built for quick audits and clean exports in multiple different formats.
