DigInterface Browser Extensions — Chrome, Edge, and Firefox

Everything you use on diginterface.com is now one click away in your browser. The DigInterface extension puts the full toolkit in your toolbar — no need to switch tabs or bookmark the site.

Available on all major browsers

What’s included

  • DNS Lookup — full record type set with pill-style selectors, matching the main site
  • Email Header Analysis — paste headers straight from your mail client
  • SSL Checker — certificate chain, expiry, and issuer at a glance
  • Blacklist Checker — scan a domain or IP against major DNSBLs
  • WHOIS — registrar, dates, and nameservers
  • SPF Expander — flatten nested includes into a single list
  • DNS Propagation — check resolution across global nameservers

Right-click, anywhere

Select a domain or IP on any page and look it up instantly. Select raw email headers and analyse them without leaving the page. Right-click a link to check where it actually points before you click it.

Getting started

When you first open the extension you’ll see a welcome panel asking for your API key. Grab one from your account dashboard with the dns and email scopes, paste it in, and you’re set.browser-extensions-hero
