BuiltWith tells you what technology a website is built with, and which websites use a given technology. Sales and marketing teams use it to build lead lists, for example every company running a competitor's software, and to prepare for conversations with prospects.
Who is BuiltWith for?
BuiltWith fits B2B teams whose ideal customer is defined by the tools they already use. A Shopify app maker can list stores on Shopify. A CRM vendor can find companies that use a rival CRM. Agencies use it to understand a prospect's stack before a pitch. If your target market has no visible footprint on the web, BuiltWith will be less useful.
What can you do with BuiltWith?
Look up any website
Type in a domain and BuiltWith shows the technologies it detects, such as analytics, content management, ecommerce, advertising and hosting. Single lookups are free, and a browser extension shows the same data while you browse.
Build lead lists by technology
Paid plans let you list every site that uses a technology or a keyword, then filter by signals such as technology spend and lifecycle events. BuiltWith says all paid plans include exportable contact names, emails and titles, with Excel and CSV export. This is the main reason sales teams pay for it, and it pairs well with account-based marketing.
Sales intelligence and CRM sync
You can track companies that adopt competitor tools and push those lists into Salesforce or HubSpot. The API and MCP tools give developers and AI agents direct access to the data.
Market analysis
BuiltWith tracks adoption trends over time. Its homepage says it covers more than 128,000 technologies and over 20 years of data, so you can see whether a technology is growing or losing users.

What do users say about BuiltWith?
BuiltWith is rated 4.3 out of 5 on G2 at the time of checking, from a fairly small number of reviews. Reviewers praise how quickly it reveals a company's tech stack and how useful that is for lead generation and more informed sales conversations. Several mention seeing a prospect's previous vendors as a helpful talking point.
The common criticisms on G2 are cost, occasional inaccurate or missing detections, and large CSV exports that take work to clean up. Some reviewers also find the interface cluttered at first.
