Overview
Fast, private on-page SEO data, exports, schema, links, images, and SERP previews for working SEOs.
Shumway SEO Toolkit inspects the current browser tab and shows page-level signals in one workspace. Open it when you need it. There is no account, and analysis never leaves your machine. FEATURES š Overview See how the page identifies itself: URL and canonical, title and description, language, H1, robots meta, response headers, and a short list of review items. š Web Vitals Measure this page in your browser, then optionally refresh Chrome UX Report field data and PageSpeed Insights lab data. Responses stay on your device until you refresh again. š Headings and Links Walk the rendered heading outline and the link list, including empty or duplicate anchors. Filter, sort, copy, or save the rows you care about. š¼ Images Review rendered images, alt text, missing dimensions, and duplicate sources. Preview files, copy URLs, and save a ZIP of selected images. š Structured Data Find JSON-LD, Microdata, and RDFa on the page, inspect parse warnings, and copy a block as pretty JSON. š¤ Robots Tools View the live robots.txt file, test a path against grouped crawlers or a custom user-agent, and see which rules matched. āļø SERP Previews Edit desktop and mobile search-result previews and save a PNG or WebP of the layout you want. āæ Accessibility and Color Inspect the rendered accessibility tree, including landmarks and controls. An optional colorblind-friendlier palette makes issue marks easier to tell apart. šØ Social and Style Preview Open Graph and X/Twitter tags, then inspect fonts, CSS variables, page colors, and stylesheets. š Webmaster Tools Open shortcuts for the current URL or site. Those sites load only when you click them. āļø JavaScript Testing Turn JavaScript off for the current site, reload, and compare what changed. š¦ Exports Save tables, page copy, image archives, and preview images in the browser. Nothing is uploaded to Shumway for those files. PRIVACY š The extension reads the active tab only after you use it. It does not send page content to Shumway servers or record analytics about your browsing.
