WebShanks Site Inspector

Run DNS and email checks for the website you are viewing.

WebShanks Site Inspector puts practical DNS, email, security, server and domain diagnostics within reach of the website you are viewing. Open the extension to detect the current domain, then run supported DNS checks directly in the browser or open the matching WebShanks diagnostic with the domain already filled in. Checks available inside the extension include: - Domain Overview with grouped DNS, email and security results - Email Health Check - MX Lookup - SPF Checker - DMARC Checker - DKIM Checker with selector input - MTA-STS Checker - TLS-RPT in Email Health - DNSSEC Checker - TXT Lookup - NS Lookup - CAA Lookup Advanced WebShanks tools include SSL certificate inspection, WHOIS lookup, SMTP testing, port checks, blacklist checks, reverse DNS, DNS propagation, disposable-email detection and email-provider detection. Additional features: - One-click Domain Overview with advanced SSL, WHOIS and blacklist actions - Automatic current-domain detection - Searchable library of 20 tools - Quick checks for common diagnostics - Favorites and recent domains stored locally - Five-minute local DNS-result caching - Refresh and copy-result controls - Right-click “Inspect with WebShanks” action - Keyboard shortcut: Alt+Shift+W - Compatible with Chromium-based Chrome and Microsoft Edge Privacy is built into the workflow. The extension extracts only the hostname from the active tab after user interaction. Inline DNS requests use encrypted DNS-over-HTTPS. Favorites, recent domains and cached DNS results remain in local browser storage. The extension does not read page content, cookies, passwords or complete browsing history. Some advanced checks require capabilities unavailable to browser extensions. Those checks open the corresponding WebShanks page only after the user selects the tool.
