LinkPulse: Broken Link & Redirect Checker

Audit broken links, 301/302 redirects, and missing #anchor targets on modern SPAs & websites with live page highlighting.

LinkPulse is a fast, local-first broken link checker, redirect chain tracer, and in-page #anchor auditor built for modern JavaScript websites, SPAs, and technical SEO workflows. Unlike legacy link checkers that miss hydrated React/Next.js/Vue links or flood your audit with false 403/999 errors from LinkedIn and Cloudflare, LinkPulse runs directly inside your browser to deliver clean, actionable results. KEY CAPABILITIES: • Hydrated SPA, Shadow DOM & Iframe Scanning — Extracts links, images, and #fragment anchors from the live rendered DOM, open Shadow roots, and same-origin iframes. • Full Hop-by-Hop Redirect Chains — Captures every intermediate 301, 302, 307, and 308 redirect hop up to the final destination URL, plus rel="nofollow" flags. • Smart Anti-Bot Separation — Automatically isolates 401 / 403 / 429 / 999 bot-wall responses into a dedicated "Protected" bucket so genuine 404 / 410 / 5xx dead links stand out immediately. • 1-Click Body-Only Content Filter — Hide repetitive <header>, <nav>, and <footer> boilerplate links to focus strictly on main article or page content. • Live On-Page Badges & DOM Spotlight — Highlights broken and redirected links right on the webpage; click "Locate" in Popup or Side Panel to scroll straight to any element. • Whole-Site Crawl & Regression Diffs — Crawl up to 50 internal pages seeded from sitemap.xml and internal links, and track newly broken vs. fixed links since your previous scan. • Developer-Ready Exports — Copy broken URLs, formatted Markdown issue tables (for GitHub/Linear), or full SEO audit CSV spreadsheets including CSS selectors. PRIVACY & PERMISSIONS BY DESIGN: • 100% Local Link Auditing — Visited URLs, page DOM, and audit reports never leave your browser. • Zero Upfront Host Permissions — Installs cleanly using activeTab, requesting cross-origin deep-check access only when you explicitly opt in. • Built-In Safety Guardrails — Automatically skips /logout, /signout, and /unsubscribe routes so scanning never logs you out of active sessions. PRICING: • Starter Trial (Free): Includes 5 full-feature single-page or multi-page audits with all filters and exports unlocked (no account required). • LinkPulse Pro: Optional upgrade ($2.60/month or $15/year) for unlimited page scans, 50-page site crawls, and exports across up to 3 browsers.
