Browser extension
WHOIS in your right-click menu.
A tiny Chromium extension that adds “Look up this domain on MokoHost WHOIS” to any link, any selected text, and the page you're on.
What it does
Right-click any link
Looks up the link target's domain in one click — no copy-paste.
Selected text or current page
Highlight any text or right-click the page itself — same shortcut, different sources.
Toolbar popup with results
Search inline and see registrar, created and expiry right in the popup — no new tab unless you want the full report.
Single-host scope
The extension only talks to whois.mokohost.com. No content scripts, no access to the pages you visit.
Install
One click to install.
Free, no signup. Works in every Chromium browser — Chrome, Edge, Brave, Arc, Opera, and Vivaldi all share the same install flow.

Permissions requested: contextMenus, storage, and host access to whois.mokohost.com only (so the popup can render results inline). No content scripts; the extension can't read other pages you visit.
