In short

This free tool scans any website and shows the technologies it runs, grouped into clean categories with logos. It also flags what the business is missing (no CRM, no chat, no reviews, no ad pixel) and frames each gap as a clear sale. No login, results in seconds.

How the tech stack detector works

Enter a website and press scan. The request runs on our server against the official BuiltWith technology profile for that domain, so the BuiltWith data key never reaches your browser. The result comes back grouped into categories like CMS, e-commerce, analytics, pixels, CDN, hosting, payments, chat, email, and CRM, each shown as a logo chip.

Every scanned domain is cached for about a month, because a tech stack rarely changes week to week. A repeat scan of the same site returns instantly and costs nothing, which keeps the tool free.

How agencies use this to find and close local businesses

Run the detector on a prospect before you ever pick up the phone. The gaps and opportunities panel is built for exactly this: it shows what the business does not have yet, and turns each gap into a concrete offer.

  • No CRM detected becomes a pitch for a GoHighLevel CRM that captures every lead in one place.
  • No chat widget becomes a pitch for an AI chat or voice agent that answers visitors and books calls around the clock.
  • No review tool becomes a pitch for review automation that asks happy customers for a Google review on autopilot.
  • No ad pixel becomes a pitch for a paid ads setup with proper tracking.

Copy the summary into your notes, send the client a shareable link to the same result, or save the branded report card as an image for your proposal. The honest framing matters: this snapshot tells you what to fix, and GoHighLevel is the always-on system to act on it.

What it detects

The detector groups results into content systems, e-commerce platforms, web frameworks, JavaScript libraries, analytics and behavior tools, ad and conversion pixels, tag managers, CDNs, hosting and servers, payment processors, chat and support tools, review and reputation tools, email senders, and CRM and marketing automation. Where a technology has its own page, the chip links to it so you can learn how to spot it elsewhere.

Frequently asked questions

What is a website tech stack detector?

A tech stack detector reads a website and reports the technologies it runs, such as the CMS, e-commerce platform, analytics, ad pixels, CDN, hosting, payments, chat widget, email tools, and CRM. It turns the hidden software behind a site into a clear, grouped list.

Is the tech stack detector free?

Yes. You can scan any website with no login and see the full result right away. There is a fair daily limit per visitor to keep it free for everyone. For unlimited scans you can start the GoHighLevel 30-day free trial through RocketLauncher.

How does the detector work?

You enter a website, and the scan runs server-side against the official BuiltWith technology profile for that domain. The result is grouped into clean categories with logos. Repeat scans of the same site are cached, so they return instantly.

What technologies can it detect?

It detects content systems, e-commerce platforms, web frameworks, JavaScript libraries, analytics, ad and conversion pixels, tag managers, CDNs, hosting, payment processors, chat and support tools, review tools, email senders, and CRM and marketing automation.

How do agencies use this to find clients?

The gaps and opportunities panel flags what a business is missing. No CRM, no chat widget, no review tool, or no ad pixel each becomes a clear pitch: a GoHighLevel CRM, an AI chat or voice agent, review automation, or a paid ads setup. Agencies run it on a prospect before the first call.

How accurate is the result?

The detector reads the public technology profile of a domain, so it is strong on widely used tools and the things sites expose in their code and DNS. It is a snapshot, not a live audit, and very new or well-hidden tools can be missed. Each detection carries a small confidence marker.
