Ever visited a website and wondered which tools or technologies power it? BuiltWith is the perfect tool for satisfying that curiosity. Whether you’re a marketer researching competitors or a web developer scouting trends, this tool reveals the full tech stack behind any site in seconds. In my tutorial, I show you exactly how to use BuiltWith effectively to uncover everything running behind the scenes.

BuiltWith works like a digital detective — scanning websites and reporting what software, hosting, analytics, and frameworks they use.

Here’s how to use it step by step:

1. Visit the BuiltWith Website
Go to builtwith.com. You don’t even need an account to start exploring.

2. Enter a Website URL
Type any domain into the search bar — for example, shopify.com or nytimes.com — and hit enter.

3. Review the Technology Profile
You’ll see detailed categories such as:

  • Analytics tools (Google Analytics, Hotjar, etc.)

  • CMS or platform (WordPress, Shopify, Webflow)

  • Marketing tech (Facebook Pixel, HubSpot)

  • Hosting provider and SSL certificates

4. Use It for Market Research
If you run a digital agency, you can use BuiltWith to identify potential leads by finding sites that use certain tools — for instance, locating all websites that use Klaviyo or WooCommerce.

5. Export Data for Deeper Analysis
BuiltWith’s paid plan allows you to download entire lists of websites matching specific technologies. This is great for prospecting or competitor tracking.

Pro Tip:
Combine BuiltWith data with tools like Hunter.io to find company contact emails and reach out for partnerships or sales opportunities.

I use BuiltWith weekly to analyze what’s trending in the online business world — from marketing stacks to emerging frameworks. It’s one of the most underrated tools for anyone who wants to understand the web at a deeper level.
