Link checker

Check HTTP status (301 / 404 …), filter by Internal / External / Nofollow / Issues, jump to any link on the page.

⚡
Core Web Vitals

Live LCP, INP, CLS, FCP and TTFB, color-coded by Google's thresholds.

🗺️
Sitemap validator

Crawl sitemap.xml (and sub-sitemaps) and list every URL that returns a redirect or error.

Changelog

Every version, newest first.

v1.4.0Jul 24, 2026Latest
  • New Issues tab — every problem found across all tabs in one prioritized list: critical first, then warnings. Click an issue to jump straight to its tab; on-demand check results (link status, image weight, sitemap) join the list once you run them.
  • The UI now speaks 8 languages — English, Українська, Русский, Español, Deutsch, Français, Português and 日本語. Auto-detects your browser language, with a manual switcher in the header.
  • Copy buttons for Title, Description and Canonical — one click, with a confirmation tick.
v1.3.8Jul 22, 2026
  • Heading structure checks — the Headers tab now flags skipped levels (e.g. H2 → H5), empty heading tags and a first heading that isn't an H1, each marked right on the heading list.
  • A summary warning on the Summary tab points to heading problems the moment you open the popup.
v1.3.7Jul 19, 2026
  • Accessibility overhaul — full keyboard navigation (arrow keys across tabs, Enter to jump to any link), screen-reader announcements for every check, and WCAG AA contrast in both themes.
  • Light theme retuned — its own deeper accent and status colors instead of reusing the dark palette; readable everywhere.
  • Sturdier network checks — link, image, headers, sitemap and domain lookups now time out instead of hanging; sub-sitemaps are fetched in parallel.
  • Fixed: over-length titles were shown with a green OK dot; broken image previews now fall back correctly.
  • On-page heading highlight colors now match the popup's color key; system dark/light preference is respected on first run.
v1.3.6Jul 14, 2026
  • ~3× faster scans on large pages — network checks and Core Web Vitals now run in parallel with page analysis instead of one after another.
  • Google Search Console quick links — open URL Inspection or the Performance report for the current page in one click (Tools tab).
  • Tools tab: Validate & audit moved up, right after “On this site”.
v1.3.5Jul 14, 2026
  • The Domain tab now shows DNS records — A, AAAA, NS, MX and TXT — resolved live over DNS-over-HTTPS.
v1.3.4Jul 13, 2026
  • New Domain tab — domain age, created / last-updated / expiry dates and registrar, via RDAP (modern WHOIS). Warns when the domain expires soon.
v1.3.3Jul 13, 2026
  • llms-full.txt detection — the Tools tab now checks for and links to both llms.txt and llms-full.txt.
  • The extension version is now shown at the bottom of the Tools tab.
v1.3.2Jul 10, 2026
  • Tools tab reorganized into clean, separated cards for easier scanning.
v1.3.0Jul 10, 2026

v1.2.xJul 10, 2026
  • Google (SERP) & social previews with the real site favicon, and Open Graph / Twitter tag validation.
