Yoke — Domain Intelligence

Instant domain intelligence — security headers, DNS, TLS certificates, and more — in a Chrome side panel. Click ⚡ on any site and get a full breakdown without leaving your tab. WHAT YOU GET Overview tab — letter grades for security headers and TLS, certificate expiry countdown, IP and nameserver info, DNSSEC status, and alerts for anything that needs attention. Headers tab — full security headers audit with grade, per-header pass/fail breakdown (CSP, HSTS, CORS, Permissions-Policy, and more), redirect chain with timing, and raw header inspection. DNS tab — every record type (A, AAAA, MX, NS, TXT, CNAME, SOA, SRV, CAA), DNSSEC validation status, and query timing. TLS tab — certificate details, grade, protocol versions, cipher suites, chain of trust, key type and size, OCSP stapling, and CT log entries. HOW IT WORKS • Click the Yoke icon in your toolbar to open the side panel • The current tab's domain is analyzed automatically • Each tab loads lazily — only the APIs you open get called • Results are cached locally (DNS 5 min, headers 15 min, certs 1 hour) • Right-click any link → "Analyze with Yoke" to scan without navigating • Type any domain directly into the input field POWERED BY THE .LOL TOOLS Each tab pulls from a dedicated, purpose-built API: • yoke.lol — composite domain scoring and intelligence • xhttp.lol — HTTP security headers and redirect analysis • ns.lol — DNS lookups with DNSSEC validation • certs.lol — TLS certificate scanning and grading Every tool is free, open source, requires no accounts, and logs nothing. PRIVACY • No accounts, no signup, no tracking • No browsing history collected • Permissions: activeTab (current domain only), sidePanel, storage (local cache), contextMenus • All source code is public: github.com/yokedotlol/yoke BUILT FOR • Web developers checking their own sites • DevOps/SRE teams verifying infrastructure • Hosting support diagnosing customer domains • Security auditors reviewing header policies • SEO specialists checking DNS and TLS configuration • Anyone curious about a domain's setup Free forever.
