BuiltWith
Finds every website using a given technology and builds lead lists by tech stack, spend and location, with an API and MCP server.
From $295/mo MCP server API
Bottom line
For agency recruiters who place talent for one platform, such as Salesforce, HubSpot or Shopify: BuiltWith lists every company whose website runs that technology, so your client prospect list is built from the stack. Free single-site lookups; lead lists from $295/mo.
Stands out for: The size and history of its web index: it tracks 127,670 technologies with usage history going back years, and can alert you when a list of sites starts or stops using one. A recruiter placing Salesforce admins can pull every company that added Salesforce last quarter, filtered by location and revenue, as a live BD list.
Watch out for: It only sees what a company runs on its public website, so back-office systems that leave no trace on the site are missed, and it says nothing about who is hiring. At $295/mo for two technologies it is expensive for a solo desk, and the API and MCP server are charged on top in credits.
Overview
BuiltWith crawls the web much as a search engine does and records the technologies on each site. It says it gets no data from third parties and tracks 127,670 different web technologies, with trend history going back more than 18 years.
Anyone can look up a single website for free. Paid plans add lead lists of every site using a technology, filtered by spend, revenue, location, industry and homepage keywords, plus exports to CSV or Excel and alerts when sites add or drop a technology.
Paid accounts also get company contact details where they are publicly listed, estimated monthly technology spend, ecommerce revenue estimates, and CRM enrichment for Salesforce, HubSpot, Microsoft Dynamics 365, Zoho, Pardot and Close.
Developers and AI users can reach the same data through the BuiltWith API, a hosted MCP server at api.builtwith.com/mcp and SDKs, all billed in API credits. Plans can be cancelled from the account at any time and stay active to the end of the paid term.
