Vantic Sales Toolkit

A Chrome extension for agencies. It names what any website runs on, grades how well it’s built, and finds the businesses on Google Maps without a site at all.

The Vantic Sales Toolkit names the technology behind any website, more than 7,600 of them, down to the theme and plugins.

It grades how well a site is built, on the page you already have open, and Lead Finder keeps the businesses on Google Maps with no website, scored and ready to work. Eight tools work from Chrome’s side panel and a full-width dashboard.

What it does, and how it’s built.

What it does

Website Analyzer. Names what any HTTPS site runs on, from more than 7,600 technologies, with versions.
Site Audit. Accessibility, SEO basics, Core Web Vitals, security headers, cookies, schema, ad pixels and more, graded in the background.
Domain & Email Health. The mail provider, sending platforms, DMARC policy, DNS host and certificate issuer behind a domain.
Lead Finder. Reads the Google Maps results you search and scroll, and keeps the businesses with no website as leads scored 0–5.
Targeting. Decides which businesses count as a lead, from built-in presets such as No-Website Gold or rules of your own.
Pipeline. Statuses, tags, notes, follow-up dates and pins for every lead, with CSV, JSON and Excel export.
Competitor Teardown. A lead set beside up to three competitors, with the verdict written and a branded one-page PDF.
Site Cloner. One page saved for offline review, with a BLUEPRINT.md that documents it for a rebuild.

How it’s built

Vanilla JavaScript on Chrome’s Manifest V3, with zero runtime dependencies and 77 test files.

What it won’t do.

In its own words, from its public product page.

It won’t contact anyone.
It finds and qualifies the business. Every call and email is yours to make.
It won’t send us your list.
Leads, notes and settings stay in Chrome on your computer, and there’s no telemetry.
It won’t hide a failed check.
A check that can’t run on a page shows as failed, never as a score.
It won’t phone home.
No analytics. The only lookups it makes on its own send a hostname to Google’s public DNS and crt.sh.
