Technographic data for local businesses

Technographic data is the list of tools a business runs. Big B2B platforms sell it for large companies; for a plumber, a dentist or a restaurant, the website is where it shows. A booking widget, a chat bubble or a call tracking script tells you how the business gets customers today, and what it is missing.

How agencies use it

No online booking: pitch a scheduling setup or a new site with booking built in. A dated website builder: pitch a redesign. Ad pixels but no call tracking: they pay for ads without knowing which calls they bring. No chat or review widget: offer lead capture and reputation tools.

How it works

The checker makes one request to the public homepage and matches its HTML, scripts and headers against known signatures, the same technique tools like Wappalyzer use. It only reads what any visitor's browser receives. Tags loaded later by Google Tag Manager or after cookie consent may not appear.

Frequently asked

What is a website technology checker?expand_more

A tool that reads a website's public code and tells you which products it is built with: the CMS or website builder, plus the third-party tools embedded in the page, such as booking widgets, chat, review widgets, call tracking, email forms, analytics and ad pixels.

How do I find out what technology a website uses?expand_more

Enter the address above and run the check. We load the homepage once and match its HTML, scripts and headers against known signatures. By hand, you can view the page source and look for script hosts such as assets.calendly.com or cdn.callrail.com.

What is technographic data?expand_more

Technographic data describes the technology a company uses, the way firmographic data describes its size or industry. For agencies it answers questions like "which dentists in Austin have no online booking" or "which restaurants are on Wix".

Can it detect booking systems and chat widgets?expand_more

Yes. It recognises Calendly, Acuity Scheduling, Square Appointments, Booksy, Vagaro, Mindbody, OpenTable, Resy and Tock, chat tools such as Podium, Birdeye, Tidio, LiveChat, Intercom and Drift, and the other tools listed on this page.

Why is a technology I know about missing?expand_more

The check reads the homepage only. Tools that load later through Google Tag Manager, after a cookie banner, or only on inner pages may not appear, and custom or uncommon tools may not be in the list yet.

Is the website technology checker free?expand_more

Yes, free and without signup, for one site at a time. To get lists of local businesses filtered by the technology they use or don't use, try LeadWebia.
