Green π: site.querySelectorAll

About

Ever needed to know which pages of a site have a broken <h1>, a missing meta tag, or a specific
piece of text? "Green π" lets you scan an entire website and then search it like a database —
right from your browser's side panel.

── HOW IT WORKS ──
1. Open the side panel on any website
2. Click "Scan site" — the extension reads the sitemap and downloads all pages into local storage
3. Run any number of searches instantly against the cached pages — no re-downloading

── SEARCH TYPES ──
• CSS selector — find every page where document.querySelectorAll('your selector') returns results
  Example: "img:not([alt])"  →  all pages with images missing alt text

• XPath — full XPath 1.0 support for precise structural queries
  Example: "//h2[not(preceding-sibling::h1)]"  →  pages where H2 appears before any H1

• Text search — case-insensitive full-text search across visible page content
  Example: "contact us"  →  all pages mentioning that phrase

• Source search — raw HTML search, catches inline styles, comments, data attributes
  Example: "<!-- Google Tag Manager -->"  →  verify tracking is present on every page

── RESULTS ──
Each result shows the page title, URL and match count.
Hit "Open all" to open every matched page in new tabs at once or copy/export results for use in another app.

── WHO IS THIS FOR ──
✔ Front-end developers auditing markup consistency across large sites
✔ SEO specialists hunting for missing tags, duplicate content, broken structure
✔ QA engineers verifying that a feature or widget is present on the right pages
✔ Content managers searching for outdated copy that needs updating

── PRIVACY ──
All scanned content is stored locally in your browser using IndexedDB.
Nothing is sent to any server. No accounts, no tracking, no cloud.
