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.














Hey Product Hunt 👋
I’m Brian, a Growth PM focused on SEO at large marketplaces. I spend a lot of time digging through on-page and technical SEO details, and I built a browser extension to make that less painful because what existed on the market didn’t give me what I needed in the formats I wanted.
Shumway SEO Toolkit is a local-first extension for page-level inspection. There are no accounts, analytics, telemetry, or tracking of any kind. It can observe page status codes and redirects for the active browser session, but full page analysis only runs when you open the toolkit or use an explicit action. It works privately on dev, staging, and production sites.
Click the extension and you get a structured workspace covering metadata, indexability signals, source-vs-rendered checks, headings, links, images, structured data, social metadata, page styles, HTTP trace details, accessibility details, SERP previews, robots.txt behavior, exports, and webmaster-tool shortcuts. It all runs from the active tab and reads the rendered page locally.
A few specifics:
📡 HTTP Trace: status codes, response headers, redirects, final response details, and exportable trace reports.
📋 Headings and links: full heading outline, internal/external link data, rel attributes, empty anchors, duplicate anchors, filters, sorting, and exports.
🖼 Images: alt text coverage, lazy loading, missing dimensions, duplicate sources, previews, selected downloads, and image ZIP exports.
🗂 Structured data: JSON-LD, Microdata, and RDFa detection, with local parse status, schema exports, and rich-result guidance.
✏️ SERP previews: editable desktop and mobile previews, exportable as PNG/WebP.
🤖 Robots tools: view live robots.txt, test any URL, compare crawler user agents, edit a local draft, and export selected crawler results.
🛠 Webmaster shortcuts: jump straight to Google Search Console, Bing Webmaster Tools, PageSpeed, Archive.org, and other SEO workflows for the current page or site.
♿ Accessibility and style: rendered accessibility tree with issue locators and JSON export, plus fonts, CSS variables, page colors, and an optional accessible color palette.
Exports are local: CSV, TSV, JSON, Markdown, page-copy TXT/HTML/DOCX/ODT, HTTP trace reports, robots reports, schema JSON, image ZIPs, accessibility JSON, SERP preview images, and focused selected-result exports.
Available on Chrome, Edge, Firefox, and Safari.
does the HTTP trace capture redirects and response times accurately or just the final document status?
Finally something that doesn't ask me to sign up just to peek at a meta tag. The local-first approach and clean export options feel like what every other SEO extension should have been doing all along.
