Fast broken link checker. Finds 404s, timeouts & redirects, highlights dead links on page with 1-click CSV export.

LinkRadar is a modern, ultra-fast, and privacy-first broken link checker designed for webmasters, SEO experts, QA testers, and developers. Audit any webpage in seconds, identify broken links (404/500), detect redirects (301/302), and inspect image assets with zero layout shift and zero false positives. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔥 WHY LINKRADAR OVER OUTDATED EXTENSIONS? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Zero False Positives (Smart HEAD → GET Fallback): Unlike older extensions that fail when Cloudflare, AWS, or CDNs block HEAD requests, LinkRadar automatically retries with a lightweight GET stream probe. Only genuinely dead links are flagged. • Non-Destructive In-Page Visual Highlights: Outlines valid (green), broken (crimson), and redirected (amber) links right inside the live webpage without breaking layout grids or moving elements. • Interactive Click-to-Locate: Click any link in the extension dashboard to instantly auto-scroll the page directly to that element with an animated pulsing radar ping. • Controlled Network Concurrency: Throttled multi-threaded queue (customizable 1–15 threads) protects your connection from browser freezing and avoids HTTP 429 (Too Many Requests) server bans. • 1-Click Client-Ready CSV Export: Download formatted audit spreadsheets containing Status Code, Anchor Text, URL, Internal/External tag, and latency in one click. • 100% Free & Privacy-First: No cloud backends, no user accounts, no telemetry, and no databases. All network requests are executed 100% locally inside your browser. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✓ Real-Time Stream Audit: Live progress bar, speed metrics, and dynamic counters. ✓ Quick Bento Filters: One-click filtering for Broken, Redirects, Warnings, or Valid links. ✓ Instant Search: Filter hundreds of links by URL or anchor text in real-time. ✓ One-Click "Copy Broken": Immediately copy all broken links to clipboard for Jira, Slack, or Trello. ✓ Image Asset Audit: Detect broken <img> source paths alongside regular hyperlinks. ✓ Smart Deduplication: Identical URLs across headers/footers are probed once and updated everywhere. ✓ Manifest V3 Compliant: Built on Google's latest high-security extension standard. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 HOW TO USE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1.
