Green π: site.querySelectorAll

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.
