BulkProbe

Browser extension

Check any site from the right-click menu, the popup, or watch its health from the toolbar badge.

What it does

  • Right-click a page or a link → check its SSL, HTTP status, DNS or registration right now.
  • Popup with a domain field and buttons for every tool — results open as shareable links.
  • Toolbar badge turns red when the current site has SSL or HTTP problems; disable it in one click.
  • No accounts, no browsing history, no remote code: the extension only talks to this service when you run a check.
